Chapter 1: FUNDAMENTAL CONCEPTS OF THERMODYNAMICS
... When a path is completely specified then the change of state is called a process. A system is in thermodynamic equilibrium if there is no change in any thermodynamic properties of a system where it is isolated from its surroundings A quasi static process can be viewed as a sufficiently slow process ...
