... • A system is any collection of objects that is convenient to regard as a unit, and that may have the potential to exchange energy with its surroundings. - What is a “status” of a system? • A status is to describe the states of a system. It does not depend on the history of the system, rather it onl ...

Thermodynamics
... When a system gains heat, the internal energy of the system increases. Q is positive when a system gains heat and negative when a system loses heat. Internal energy of a system can decrease if the system does work on its surroundings. Work is positive when it is done by the system and negative when ...

... The Helmholtz free energy F is the corresponding term at constant volume, when H is replaced by U in equation 9. A process can occur spontaneously if it leads to a reduction in the free energy. Quantities such as H, G and S are path independent and therefore are called functions of state. More About ...
