There are two classes of processes involved: Quasi-equilibrium or reversible processes, and non-equilibirium or irreversible processes. Classical thermodynamics is involved chiefly with the first of these. |

A thermodynamic system is a quantity of matter described by a set of properties. Unlike classical therodynamics, these properties may be non-uniform and may vary throughout the sample.
V (Volume)
This involves geometric definitions and the physical boundaries of a state.
P (Pressure)
This involves a mechanical definition
T(Temperature)
This can be defined using statistical mechanics.
E (internal energy)
This can be defined using statistical mechanics, and changes in it can be computed using quantities of work and heat
S (Entropy)
Changes in entropy can be defined as heat(reversible) / T.
H (Enthalpy)= E + PV
A (Helmoholtz Free energy) = E - TS
G (Gibbs Free energy) = E + PV - TS
