... C. Heat and work 1. A system can absorb heat (Q) from the surroundings. Q > 0, if heat is absorbed by the system. Q < 0, if heat is evolved from the system to the surroundings. Heat appears only at the system boundary. Heat appears only during a change of state. Strictly speaking, it is incorrect t ...

Thermodynamic Laws/Definition of Entropy Carnot Cycle
... cP > cV because the volume expands at constant pressure and the system does work which means it stores less energy. Note that for non P V T systems analogous heat capacities can be defined. In a magnetic system, P → H and V → M and we can define cH and cM . A statistical approach can be used to obta ...
