What is constant volume

Web. Web. Web. Is volume constant in adiabatic process? The assumption that a process is adiabatic is a frequently made simplifying assumption. 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.
