Questions about Heat

Postby Luis De La Cruz 1H » Mon Jan 15, 2018 10:47 am

I'm still confused about the topic of heat. Is heat a type of energy, or is heat the term we use to describe a transfer of energy?

Heat refers to energy that is transferred. The type of energy would not be heat, but thermal energy.

The book does a really good job of explaining this difference on page 268. Which is says:

Do not confuse "heat" and "thermal energy." Heat is energy in transit as a result of a temperature difference. Thermal energy (the energy of thermal motion) is the energy associated with the chaotic motion of molecules at temperatures above absolute zero.

Also, when we discuss enthalpies, we're talking about heat released or absorbed in chemical reactions.
