# 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.
