At absolute zero temperature, the kinetic energy of gas molecules theoretically becomes:

Mean kinetic energy per degree of freedom of gas molecules is

The pressure is $P,$ volume $V$ and temperature $T$ of a gas in the jar $A$ and the other gas in the jar $B$ is at pressure $2P,$ volume $V/4$ and temperature $2T,$ then the ratio of the number of molecules in the jar $A$ and $B$ will be

The average kinetic energy of a helium atom at ${30^ \circ }C$ is

At ${0^ \circ }C$ the density of a fixed mass of a gas divided by pressure is $x.$ At ${100^ \circ }C,$ the ratio will be

Kinetic theory of gases provide a base for

If pressure of $C{O_2}$ (real gas) in a container is given by $P = \frac{{RT}}{{2V - b}} - \frac{a}{{4{b^2}}},$ then mass of the gas in container is

Mean free path of a gas molecule is

An ideal gas has molecules with 5 degrees of freedom. The ratio of specific heats at constant pressure $\left( {{C_P}} \right)$ and at constant volume $\left( {{C_V}} \right)$ is:

The kinetic energy of one gram molecule of a gas at normal temperature and pressure is $\left( {R = 8.31\;J/mol - K} \right)$

At ${0^ \circ }C$ the density of a fixed mass of a gas divided by pressure is $x.$ At ${100^ \circ }C,$ the ratio will be
