A monoatomic gas undergoes a process in which the pressure $(P)$ and the volume $(V)$ of the gas are related as $P V^{- 3} =$ constant. What will be the molar heat capacity of gas for this process?

Options:

Answer:

Solution:

$P V^{- 3} = c o n s t a n t n = - 3$

$C = \frac{R}{γ - 1} - \frac{R}{n - 1} γ = \frac{5}{3}$

$C = \frac{R}{\frac{5}{3} - 1} - \frac{R}{- 3 - 1}$

$= \frac{3 R}{2} + \frac{R}{4}$

$= \frac{7}{4} R$
