The coefficient of thermal conductivity of a metal rod depends on its

A sample of gas at temperature $T$ is adiabatically expanded to double its volume. The work done by the gas in the process is (given, $\gamma = \dfrac{3}{2}$):

Energy of a gas/litre is $600$ joule, then what will be its pressure?

According to law of equipartition of energy the molar specific heat of a non rigid diatomic gas at constant volume is
