The initial pressure and volume of an ideal gas are $P_{0}$ and $V_{0}$ . The final pressure of the gas when the gas is suddenly compressed to volume $\frac{V_{0}}{4}$ will be:

(Given $γ$ = ratio of specific heats at constant pressure and at constant volume.)

Options:

Answer:

Solution:

As the gas is suddenly compressed the process is adiabatic.
So, $P V^{γ} = constant$
$\Rightarrow P_{0} V_{0}^{γ} = P \cdot {(\frac{V_{0}}{4})}^{γ}$
$\Rightarrow P = 4^{γ} \cdot P_{0}$
