One mole of an ideal monatomic gas undergoes a process described by the equation $P V^{3} =$ constant. The heat capacity of the gas during this process isNEET 2016 (Phase 2)

Options:

Answer:

Solution:

$P V^{3} =$ constant polytropic process with $n = 3$

$C = C_{v} + \frac{R}{1 - n}$

For monoatomic gas : $C_{v} = \frac{3 R}{2}$

$C = \frac{3 R}{2} + \frac{R}{1 - 3}$

$= \frac{3 R}{2} - \frac{R}{2}$

$= \frac{2 R}{2}$

$C = R$
