The initial pressure and volume of an ideal gas are $\displaystyle \mathrm{P}_{\mathrm{o}}$ and $\displaystyle \mathrm{V}_{\mathrm{o}}$. The final pressure of the gas when the gas is suddenly compressed to volume $\displaystyle \frac{\mathrm{V}_{\mathrm{o}}}{4}$ will be :
(Given $\displaystyle \gamma=$ ratio of specific heats at constant pressure and at constant volume)
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle \mathrm{P}_{\mathrm{o}}(4)^\gamma$
