Passage / Comprehension

An amount $Q$ of heat is given to ideal monoatomic gas in a process in which the gas performs a work $\frac{Q}{2}$ on its surrounding

The P-V equation of the process is

Answer:

Solution:

Polytropic: $C = C_{V} + \frac{R}{1 - n}$ with $C = 3 R, C_{V} = \frac{3 R}{2}$ .

$3 R = \frac{3 R}{2} + \frac{R}{1 - n} \Rightarrow 1 - n = \frac{2}{3} \Rightarrow n = \frac{1}{3} : P V^{1/3} = const.$
