Source: en.wiktionary.orgIsochoric 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. Source: Internet
The first is an isochoric adiabatic work process that adds to the system's internal energy. Source: Internet
Then an isochoric and workless heat transfer returns the system to its original state. Source: Internet
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. Source: Internet
