Why does heat transfer from hot to cold? (Physics)

166 ratings | 21542 views
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.

Superb video👏👏👏 But, it would be better if u did it little slower and made the video a bit longer. Anyway, I love ur work....😄

one of the best understanding video ever saw thanks friend

Completely wrong title , Why does heat transfer from hot to cold? It has never been explained why? why not slow moving atoms transfer their energy to make the fast moving atoms even faster? why is it always the other way around?

Muhammad Wasif completely stupid comment*

Think of it as a rolling ball and a stationary ball.. Can the Stationary ball transfer any motion or energy to the moving ball, no

+FactTap if there was nothing before the big bang and the big bang was infinitely hot where did the cold come from???? if heat goes to cold how could cold absorb all that heat???
