Question
An ideal gas undergoes a process in which its pressure and volume are related as PV n = constant, where n is a constant. The molar heat capacity for the gas in this process will be zero if
Options
A.n = $\gamma$
B.n = $\gamma$ – 1
C.n = $\gamma$ + 1
D.n = 1 – $\gamma$
Solution
$C_{m} = \frac{R}{\gamma - 1} + \frac{R}{1 - n} = 0 \Rightarrow \gamma - 1 = - (1 - n) \Rightarrow n = \gamma$
