Textbook says that entropy is a measure of energy unavailable to do work. For a crystal, entropy will increase with temperature, which, according to the definition, seems to mean that the useless energy increases. but, on the other hand, the quantity of heat energy available to do work depends on the temperature difference of two heat resources, and, thus, does not necessarily increase. I think I might mix something up here, and could you help me out?
