7. The Second Law and the Concept of Entropy
... No process is possible whose sole result is the transfer of heat from a body of lower temperature to a body of higher temperature. Spontaneously, heat cannot flow from cold regions to hot regions without external work being performed on the system, which is evident from ordinary experience of refrig ...

The Laws of Thermodynamics
... energy at the temperature of the environment, even when it isn't used to perform useful work, e.g., as in flashlight batteries. The second law can also be stated as: -"A process whose only effect is a local lowering of entropy cannot exist." This means that a local lowering of entropy can occur, but ...

Thermodynamics of ideal gases
... The First Law states that the energy is unchanged under any process in an isolated system. This implies that the energy of an open system can only change by exchange of heat or work with the environment. We actually used this law implicitly in deriving the heat capacities and the entropy. The Second ...

Thermodynamic functions - Phase Transformations Group
... 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 ...
