Question

Can we define all state values during an irreversible process?

Answer 1

Answer:

The work is a function of the process taken and the energy is a function of the state. The change in energy happens to coincide with the work of the process for reversible adiabatic processes but not for irreversible ones.

Explanation:

An example of an irreversible process is electric current flow through a conductor with a resistance. An example of an irreversible process is magnetization or polarization with hysteresis. An example of an irreversible process is inelastic deformation.
