Isochoric work is irreversible. citation The second law of thermodynamics observes that a natural process, of transfer of energy as work, always consists at least of isochoric work and often both of these extreme kinds of work.
The first is an isochoric adiabatic work process that adds to the system's internal energy.
Then an isochoric and workless heat transfer returns the system to its original state.
The other extreme kind of work is isochoric work ( ), for which energy is added as work solely through friction or viscous dissipation within the system.
