Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Physical Sciences Thermodynamic and Statistical Physics
A box, separated by a movable wall, has two compartments filled by a monoatomic gas of \(\frac{C_p}{C_v} = \gamma\) Initially the volumes of the two compartments are equal, but the pressures are 3P0 and P0 respectively. When the wall is allowed to move, the final pressures in the two compartments become equal. The final pressure is
1
\(\left(\frac{2}{3}\right)^\gamma P_0\)
2
\(3\left(\frac{2}{3}\right)^\gamma P_0\)
3
\(\frac{1}{2}\left(1+3^{1 / \gamma}\right)^\gamma P_0\)
4
\(\left(\frac{3^{1 / \gamma}}{1+3^{1 / \gamma}}\right)^\gamma P_0\)
