Work-done during adiabatic expansion is given by (where p1 v1, T1 = Pressure, volume and temperature for the initial condition of gas, p2, v2, T2 = Corresponding values for the final condition of gas, R = Gas constant, and γ = Ratio of specific heats)

Work-done during adiabatic expansion is given by (where p₁ v₁, T₁ = Pressure, volume and temperature for the initial condition of gas, p₂, v₂, T₂ = Corresponding values for the final condition of gas, R = Gas constant, and γ = Ratio of specific heats)
