Heat Transfer - Conduction, Convection, and Radiation
 
11:09
This physics video tutorial provides a basic introduction into heat transfer. It explains the difference between conduction, convection, and radiation. Conduction occurs when heat transfers from one material to another by direct contact. Touching a hot stove is an example of heat conduction. Heat flows from a region of high temperature to a region of low temperature or from hot to cold. Materials such as metals and diamond conduct heat very well. Wood and fiberglass do not conduct heat very well and are called insulators. still air is an insulator. Convection occurs when heat is transferred through a fluid in motion such as moving water or a wind. Hot air rises and cold air descends due to difference in density. Cold air is heavier than hot air. The last method of heat transfer is radiation. Heat from the sun travels through empty space by means of electromagnetic waves such as infrared, UV light, and visible light.

HEAT TRANSFER:Heat is a form of energy which can be transferred from one part of the system to another part, due to temperature difference between them.Heat can be transferred from one place to another by the following three modes. 1 Conduction 2 Convection 3 Radiation.CONDUCTION:-It is a mode of transfer of heat energy from one part of a body to another part at lower temperature, without actual motion of the molecules.Explanation:According to kinetic theory, the molecules of a solid are in a state of oscillation about their fixedpositions. When one end of a metal rod is heated, the molecules at heated end absorb energy. Therefore,they vibrate about their equilibrium position and interact with neighbour molecules. Thus they transfer a part of their energy to neighbour molecules. These new molecules inturn transfer energy to other molecules and so on.Thus heat energy is passed along the rod from molecule to molecule without changing their fixedpositions. Conduction usually takes place in solids copper, silver, Gases are poor conductors and liquids have conductivities intermediate between solids and gases.Mercury being a liquid metal is a good conductor. THERMAL CONDUCTIVITY:Thermal conductivity of a solid is a measure of the ability of the solid to conduct heat through it.Consider a metallic bar of length L and uniform crosssection A with its two ends in thermalcontact with large reserviors at temperature TC and TD.Heat is conducted through the bar from hot end to the cold end of bar.After some time, a steady state is reached, the temperature of bar decreases uniformly withdistance. The reservoir at C supplies heat at constant rate through the bar and is giving out at same rate to reservoir at D.During steady state, the rate of flow of heat H α directly proportional to AArea of cross section H α TC --TDtemperature different H α 1 by L (ength of bar H = kA into TC --TD by L, where TC --TD by L is called temperature gradient The constant K is called the coefficient of thermal conductivity of material of bar K = H by A into TC --TD by L, If A = 1, TC --TDby L = 1 Therefore, K =H by A units: W minverse kinverse Therefore, Coefficient of thermal conductivity of material is equal to rate of flow of heat per unit areaper unit temperature gradient across the material.The value of K depends on nature of material of the solid.The value of K is large in case of good conductors and is small in the case of insulalors.

The Heat: President Xi travels to Africa Pt 1
 
15:35
Four visits in five years – Chinese President Xi Jinping has made Africa a priority of his presidency. This time, he’s visiting Senegal, Rwanda and South Africa before a stopover in Mauritius. He visited the United Arab Emirates on his way to the African continent. African leaders are eager to greet the Chinese president as the promise of Chinese investment means access and opportunity for their people. While some critics warn that China’s involvement on the continent is a modern form of colonialism, many African leaders welcome the economic partnerships. To discuss President Xi’s visit: Chen Chenchen is deputy director of the Macro Research Department in the Chongyang Institute for Financial Studies at Renmin University. Abdullahi Boru Halakhe is a security and policy analyst focusing on Africa. Alexander Demissie is founding director of the China Africa Advisory.

Henry Tropi-Cool 887 - A Study in Heat Reduction on a Eureka Truck Camper
 
11:46
For those not familiar with Henry Tropic-Cool, it has been around for decades and is considered the best product for reducing heat on metal roofs from sun exposure. It is 100% silicone and much like the oven mitts made from the same material, heat just doesn't pass through it very well. It's also bright white so it's quite reflective also. Add the fact that it sticks like glue and is 100% waterproof and you've got the ideal coating for any RV with a metal roof. I'm not sure about other surfaces that it is compatible with but I know it's the coating of choice for all the school bus conversions. It's also the most expensive at around $65 for 0.9 gallons. It's a bit difficult to apply especially if you can't stand on the roof as was my case. That being said, this video will attempt to document the incredible effectiveness of the product. Every attempt was made to keep variables to a minimum but taking measurements over several days with almost constant temperatures and variable cloud cover makes the data very interesting if not perfectly precise.

Conduction, Convection, and Radiation [SONG!]
 
03:54
A Rap of Conduction, Convection, and Radiation done for a school project Sources: Idea & Song from: http://www.teachertube.com/viewVideo.... http://www.educationalrap.com/song/ra... Still having trouble remmebering? Here is a mnemonic: 1. Conduction has the word "duck" in it, so the molecules have to duck each other. Heat by collisions. 2. Convection has a "vec" in it, which sounds like the beginning of "vacation," which reminds me of the beach, which reminds me of fluids. Heat by fluid movement. 3.Radiation sounds like radio, which is a electromagnetic wave. Heat by EM waves." Lyrics: Chorus There are three ways that heat can travel But it can travel in any direction From the sun it moves to the earth, quick as a shadow And disperses in radiation, conduction, and convection Verse I First things first, let's discuss heat What it is before you pay for it to warm your feet Heat is the energy that flows when atoms and molecules move It diffuses out toward coolness Temperature is the measurement of The average motion of these atoms And molecules in the atmosphere So there have it Now, the first way of transportation of heat energy is radiation Like sound waves from your radio stations Filling the empty space around you Your radiator warms you, but don't start a fire now, I warned you Heat is going through radiation from the sun Before it burns you from 93 million miles away To re-radiate this heat is what the earth does for you This is survival what this heat is going through Before it rises to the sky and it's gone so... Chorus Verse II Conduction is the second method on my list You can feel it like a hot pot on your fist With the handle gripped I bet you'd rather grab a candle lit 'Cause it's heat through conduction that causes this Atoms in matter in a fixed position vibrate when heated Like a pan in the kitchen Transmit the heat energy to atoms next to them That are cooler than they are to cause equilibrium To even out the temperature the heat has to travel Up the spoon in your tea in the morning with your bagel It might burn your hand, but just learn the land of conduction heat energy until you understand The earth gains little from conduction It's mostly radiation that helps us function and keeps us warm It's just another way for heat to move But now let's move on to method three to prove... Chorus Verse III Convection is the movement of heat in liquids and gasses To even out the temperature fastest This process is called diffusion It's a flow of particles cold and hot in a fluid If you're not listening, then stop what you're doing 'Cause this final mode that heat can move in And this affects you everyday It's the breeze at your back and the wind at your face When heat reaches the earth it rises at a rate With the air in the place and it moves up till it cools Trillions of molecules together Make up the weather that we see on the news It's how they measure the pressure of the air and the temperature But convection is how it got there in the atmosphere So don't be scared. Heat moves in three ways So we made things clear, it's like...

What is Heat?
 
01:27
What is Heat? This is one of those really simple questions that is both simple and complex at the same time. Everyone has felt heat, but what is it? The simple answer is that heat is a form of energy. Heat travels in waves that we know as infrared radiation. Heat moves from a hotter body to a colder one and it does so by emitting infrared radiation.

Why does heat transfer from hot to cold? (Physics)
 
01:05
Welcome to FactTap! In this video we answer the question: WHY DOES HEAT TRANSFER FROM HOT TO COLD? Heat is a form of energy. When energy is added to atoms they begin to move very rapidly. Think of it like kinetic energy. When you push a ball (or add energy to it), it rolls. This means that the more motion atoms have, the hotter they feel to the touch. Back to the ball example. If you have a stationary ball and you impact it with another ball, the energy of the rolling ball is transferred into the stationary ball, causing it to move. You would say that the stationary ball absorbed the faster balls energy. It wouldn’t be right or sound right to say that the stationary ball transferred its stationary state to the rolling ball. The same is said about atoms transferring energy. The fast moving atoms impact slow moving (cold) atoms, transferring their kinetic energy. Therefore, to say heat transfers from hot to cold really means that energy is transferred from fast moms to slow moving atoms.

HEAT TRANSFER:CONVECTION:-It is a mode of transfer of heat from one part of medium to the another by the actual movement of particles from a region of high temperature to a region of lower temperature.Convection usually takesplace in fluids i.e liquid & gases.The rate of flow of heat due to convection. H= hA Δ T where, ΔT is temperature difference H is heat current due to convection, A is surface area. TYPES OF CONVECTION:1.NATURAL CONVECTION:If a fluid when heated, flows due to different in density, then it is called natural convection.In this convection, gravity plays important role in the formation of convection currents.EXAMPLE:-1 When a liquid in container is heated, the liquid at the bottom gets heated. Its density decreases and rises up. At the same time denser cool liquid will move down. Thus convection currents are set up in the liquid and whole liquid is heated by actual movement of particles. EXAMPLE:-2 SEA BREEZE:Explanation: During the day, the ground heats up more quickly than water in sea, because waterhas a greater specific heat. The air in contact with the warm ground is heated by conduction. It expandsand becomes lighter. As a result, the warm air rises up, resulting air currents and cool air moves down tofill the space. This creates a sea breeze.In this way thermal convection cycle is set up, which transfersheat away from land.At night, the ground loses its heat more quickly than sea water. Due to it, the water surface iswarmer at night than that of ground. As a result of it, the land breeze is set up and thermal convection cycle is reversed.At night, the ground loses its heat more quickly than sea water. Due to it, the water surface iswarmer at night than that of ground. As a result of it, the land breeze is set up and thermal convection cycle is reversed. 2. FORCED CONVECTION:If the heated fluid is forced to move away then it is called forced convection.Example: Heating or cooling rooms by a mechanical pump, blood circulation in the body.RADIATION:It is a mode of transmission of heat from one place to another, without requiring any material medium.Heat from sun reaches to earth through the phenomenon of radiation.The heat energy transferred by radiation is called radiant energy. This energy is in the form of electromagnetic waves. The electromagnetic radiation emitted by a body by virture of its temperature is called thermal or heat radiation infrared radiation. These radiations are not visible but they produces the sensation of warmth. Heat radiation or thermal radiation can travel through vacuum with the speed of light.

Convection of heat Experiment - Elementary Science
 
01:33
This is an elementary science video that explains Convection of Heat for Grade 7-8 kids. CONVECTION OF HEAT Take a round-bottomed flask. Put some crystals of Potassium Permanganate in it. Pour water into the flask gently so as not to disturb the crystals much. Heat the flask gently. Water molecules go up from the level of Potassium Permanganate reach the surface of the water and come down touching the sides of the flask. After a few minutes the crystals of Potassium Permanganate dissolve in water making it coloured violet. The water at the bottom gets heated and expands. The density of water becomes less because of this expansion, therefore water becomes light and goes up to the top. At the top the cool water which has more density comes down by the sides of the flask. You can observe that the colored water going up in the middle and coming down along the sides of the flask. Molecules absorb heat go up and the cool molecules come down absorb heat and go up. In this way heat gets transferred from one place to another. This process is called convection of heat. The difference in the densities of different parts of the substance is responsible for the phenomenon of convection of heat.

01:31
In this activity we explore how conduction works. We affix pins on a metal spoon with the help of some molten wax. As we heat the spoon, we observe that the pins fall of one after another, staring from the pin that was closest to the spirit lamp. This method of heat transfer is called conduction and takes place only in solids. In conduction the particles in the object transfer heat without moving from one place to another in the object.

The Heat: President Xi travels to Africa Pt 2
 
11:49
Four visits in five years – Chinese President Xi Jinping has made Africa a priority of his presidency. This time, he’s visiting Senegal, Rwanda and South Africa before a stopover in Mauritius. He visited the United Arab Emirates on his way to the African continent. African leaders are eager to greet the Chinese president as the promise of Chinese investment means access and opportunity for their people. While some critics warn that China’s involvement on the continent is a modern form of colonialism, many African leaders welcome the economic partnerships. To discuss President Xi’s visit: Chen Chenchen is deputy director of the Macro Research Department in the Chongyang Institute for Financial Studies at Renmin University. Abdullahi Boru Halakhe is a security and policy analyst focusing on Africa. Alexander Demissie is founding director of the China Africa Advisory. Edmund Ghareeb is a scholar specializing in Middle East affairs.

How Heat Pump Operates ?
 
02:54
WHAT IS A HEAT PUMP? Technically, a heat pump is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a controlled space. Installation for this type of system typically consists of two parts: an indoor unit called an air handler and an outdoor unit similar to a central air conditioner, but referred to as a heat pump. A compressor circulates refrigerant that absorbs and releases heat as it travels between the indoor and outdoor units. HOW DOES A HEAT PUMP WORK? Think of a heat pump as a heat transporter constantly moving warm air from one place to another, to where its needed or not needed, depending on the season. Even in air that's seems too cold, heat energy is present. When it's cold outside a heat pump extracts this outside heat and transfers it inside. When it’s warm outside, it reverses directions and acts like an air conditioner, removing heat from your home. One advantage of a heat pump is that it moves heat instead of generating heat, giving you more energy efficiency. Also, it is powered by electricity, so you can save substantially on fuel consumption.Note that heat pumps are best for moderate climates, and a supplemental heating source may be needed for lower temperatures.

BioFire Fireplaces - The Heat Flow
 
00:39
This video shows how a the heat travels inside the unique core of a BioFire Fireplace. After the wood burns at close to 1.000°C, the heat generated travels through the ceramic refractory flue passages, that absorb as much energy as possible. In fact up to 90% of the energy is retained and only 10 - 15% are lost through the chimney.

Human Body Limit to Heat Stress from Abrupt Climate Change
 
15:01
The average persons core body temperature is 98.6 F (37 C). Human skin is a few degrees colder, being about 35 C (95 F). Heat travels from hot regions to cold regions, according to the Second Law of Thermodynamics. Thus when the wet-bulb temperature, which is the temperature at 100% humidity, reaches 35 C (95 C) the human body can no longer shed heat (sweat no longer evaporates), thus core body temperature rises, and the healthiest person, sitting in the shade, dies in about 6 hours. The rest of us (young, old, medicated, out-of shape, obese, etc...) are SOL at even lower wet-bulb temperatures. Adaptation would require living inside with AC, living in caves, or wearing cooled suits; who wants to do that??

Heat Pumps: World's First LEED Net Zero Home - buildaroo.com
 
02:55
Paul Rosen, the owner of this LEED home, talks about the sustainable heating and cooling of this home. This home is heated using an outdoor heat pump manufactured by Bryant. Paul explains that a heat pump is an air conditioner that can reverse its cycle, and instead of supplying the house with air that's cool, it can supply the house with air that's hot. These heat pumps were installed on the south side of the home so that based on the sun's movements, they are in the bright sun in the winter and they are in the shade in the summer. According to Paul, these heat pumps are 20% more efficient at heating when they are located in the sun. Paul explains that heat travels in 3 ways: radiant heat, conductive and convective. The reason these pumps are more effective when in the sun is because a radiant heat effect is created that would not be there otherwise.

The reason these pumps are more effective when in the sun is because a radiant heat effect is created that would not be there otherwise. With all this heat pumping, how can this home be a Net Zero home? The almost non-existent heating bill is the result of the photovoltaic (PV) panels that generate the electricity necessary to power the heat pump. These PV panels also generate extra electricity during certain months that feed into the grid, and the home takes back what it needs during the cool nights in the winter. In addition to using a heat pump to heat and cool the home, the home has a Radco storage tank and heat exchanger to supply the home's hot water. This water is heated through the home's Solar Thermal panels. About the speaker: Paul Rosen is a sustainability consultant and founder of North Bay Energy.

Hypersonic travel: New ceramic coating material can withstand extreme heat - TomoNews
 
06:51
MANCHESTER, UNITED KINGDOM — Researchers from Britain and China have developed a new ceramic material that could be used as a coating material in hypersonic planes, which allows them to withstand the extreme temperatures generated by flying at hypersonic speed. Objects travelling at hypersonic speed have to withstand surface temperatures of up to 3,000 degrees Celsius, which is enough to melt materials commonly used in current aircraft construction. The new ablation-resistant carbide is a substitutional solid solution of zirconium and titanium with boron atoms. It is made by densifying a carbon fibre preform — which is a reaction melt infiltrated to create a carbide composite — by chemical vapour infiltration using CH4 and H2 gases. The surface region of the carbide comprises of up to 75% ceramic and 25% carbon, which is dense enough to act as a barrier to resist oxidation and extreme heat of up to 3,000 degrees Celsius. Existing ultra-high temperature ceramics, such as zirconium carbide, is commercially used in tool bits for cutting tools. Researchers say the new carbide coating is 12 times better than the existing ones. The study was led by researchers at The University of Manchester in collaboration with China's Central South University. It was published in the journal Nature Communications. ----------------------------------------­--------------------- Go to https://www.patreon.com/tomonews and become a Patron now TomoNews is now on Patreon and we've got some cool perks for our hardcore fans.
