Equation of the gas state processes

Problem 2.11

Find the maximum attainable temperature of ideal gas in each of the following processes: (a) p=p0αV2p=p_{0}-\alpha V^{2} (b) p=p0eβVp=p_{0} \mathrm{e}^{-\beta V} where p0,αp_{0}, \alpha and β\beta are positive constants, and VV is the volume of one mole of gas.

Reveal Answer
(a) Tmax=2/3(p0/R)p0/3αT_{\max }=2 / 3\left(p_{0} / R\right) \sqrt{p_{0} / 3 \alpha} (b) Tmax=p0/eβRT_{\max }=p_{0} / \mathrm{e} \beta R
