	For a gas $\gamma =7/5.$ The gas may probably be
	If a gas has n degrees of freedom ratio of specific heats of gas is
	5 moles of oxygen is heated at constant volume from 10°C to 20°C. The change in the internal energy of the gas is (the gram molecular specific heat of oxygen at constant pressure, ${{C}_{p}}=8$ cal/mole °C and R = 8.3 cal/mole °C)
	What is the value of $\frac{R}{{{C}_{P}}}$ for diatomic gas
	The degrees of freedom of a stationary rigid body about its axis will be
	A gaseous mixture consists of 16g of helium and 16g of oxygen. The ratio $\frac{{{C}_{P}}}{{{C}_{V}}}$of the mixture is
	The pressure exerted by the gas on the walls of the container because
	Gas at a pressure ${{P}_{0}}$ in contained is a vessel. If the masses of all the molecules are halved and their speeds are doubled, the resulting pressure P will be equal to
	A box contains n molecules of a gas. How will the pressure of the gas be effected, if the number of molecules is made $2n$
	The relation between the gas pressure $P$ and average kinetic energy per unit volume $E$ is
