Expression for Work in an irreversible adiabatic process in terms of gamma​

Answer 1

The same can be said to be true for the expansion process of such a system. ... For such an adiabatic process, the modulus of elasticity (Young's modulus) can be expressed as E = γP, where γ is the ratio of specific heats at constant pressure and at constant volume (γ = CpCv ) and P is the pressure of the gas .
