Heat
... 1) One can refer to heat only when energy has been transferred as a result of a temperature difference. Both heat and work are ways of changing the energy of a system. 2) the internal energy of a system can be changed even when no energy is transferred by heat. For example, when a gas in an insulat ...

Latent Heat
... The process also works in reverse: when water changes from steam to water, it releases heat in the same amount. Note that some materials can change from liquid to gas at temperatures other than the boiling point – for example, when water evaporates from your skin. When water evaporates, the latent h ...
