Is heat the transfer of thermal energy
WebHeat Convection Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law).Hot water is likewise less dense than cold water and rises, … WebMay 22, 2024 · Heat is a form of energy, but it is energy in transit.
