Problem 2.135

Vessels 1 and 2 contain \(v=1.2\) moles of gaseous helium. The ratio of the vessels' volumes \(V_{2} / V_{1}=\alpha=2.0,\) and the ratio of the absolute temperatures of helium in them \(T_{1} / T_{2}=\beta=1.5\). Assuming the gas to be ideal, find the difference of gas entropies in these vessels, \(S_{2}-S_{1}\)
