curves of an ideal gas for two adiabatic processes connecting two isotherms. Fig. . P-V curves for isothermal and adiabatic processes of an ideal gas.
We can calculate, as before, the work done in an adiabatic change of an ideal gas from the state ( P , V , T ) to the state ( P , V , T ). W = P d ∫ ( . ) From Eq. ( .
), the constant is P V γ or P V W = P V P V P V P V R(T
