A gas can expanding adiabatically might stop expanding either because it has filled a rigid container (known final volume) or it has equilibrated with an external pressure (known final volume). Derive the expression for the final pressure of an ideal gas after an adiabatic expansion. Begin with the simple expression derived using the ideal gas law: PiVi Ti PfVf Tf Then use the expression for the ratio of the final temperature R/C₂ (1) The final expression is Ti Tf Pƒ = P₁ * Cp Vi Cv SIS
