Workdone 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
1
\(\frac{p_1v_1 - p_2v_2}{\gamma -1}\)
2
\(\frac{mR(T_1-T_2)}{\gamma -1}\)
3
\(\frac{mRT_1}{\gamma -1}\left(1-\frac{p_2v_2}{p_1v_1}\right)\)
