# NEET Physics Thermodynamics Questions Solved

A monoatomic gas $\left(\gamma =5/3\right)$ is suddenly compressed to $\frac{1}{8}$ of its original volume adiabatically, then the pressure of the gas will change to -

(1) $\frac{24}{5}$

(2) 8

(3) $\frac{40}{3}$

(4) 32 times its initial pressure

(4) $P{V}^{\gamma }$= constant

$\frac{{P}_{2}}{{P}_{1}}={\left(\frac{{V}_{1}}{{V}_{2}}\right)}^{\gamma }⇒{P}_{2}={\left(8\right)}^{5/3}{P}_{1}=32 {P}_{1}$
