An ideal diatomic gas (γ = 1.4) is compressed adiabatically to half its volume — JEE Physics
An ideal diatomic gas ($\gamma = 1.4$) is compressed adiabatically to half its volume. If initial pressure is $P_0$, find the final pressure.

For adiabatic process: $PV^\gamma = const$
$$P_0 V^\gamma = P_f \left(\frac{V}{2}\right)^\gamma$$
$$P_f = P_0 \times 2^\gamma = P_0 \times 2^{1.4}$$
$$P_f = P_0 \times 2.639 \approx 2.64\, P_0$$
