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, … WebThese are conduction, convection and radiation. Conduction of heat: The mode of transfer of heat by vibrating atoms and free electrons in solids from hotter to colder part of a body is called conduction of heat. Rate of flow of heat: The amount of heat that flows in unit time is called the rate of flow of heat.
