Prove that adiabatic expansion of an ideal gas from P1, V1 to vacuum with a final volume V2 (V2 > V1) is spontaneous.
Added by Jeremy T.
Step 1
Step 1: Start with the equation for entropy change: \(\Delta S = \frac{Q}{T} = \frac{T_2}{T_1} + R \ln\left(\frac{V_2}{V_1}\right)\) Show more…

Show that $$ P_{1} V_{1}^{\left(\bar{C}_{V}+R\right) / \bar{C}_{V}}=P_{2} V_{2}^{\left(\bar{C}_{V}+R\right) / \bar{C}_{v}} $$ for an adiabatic expansion of an ideal gas. Show that this formula reduces to Equation $19.23$ for a monatomic gas.
Show that $$ \left(\frac{T_{2}}{T_{1}}\right)^{3 / 2}=\frac{\bar{V}_{1}-b}{\bar{V}_{2}-b} $$ for a reversible, adiabatic expansion of a monatomic gas that obeys the equation of state $P(\bar{V}-b)=R T$. Extend this result to the case of a diatomic gas.
