How many moles of water vapor are present in 5600 L at STP?

Two gases $A$ and $B$ having same pressure $p$, volume $V\;$ and absolute temperature $T$ are mixed. If the mixture has the volume and temperature as $V$ and $T$ respectively, then the pressure of the mixture is

The mean free path of a gas is inversely proportional to:

The ratio of mean kinetic energy of hydrogen and oxygen at a given temperature is

The rate of diffusion is

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

The temperature of an ideal gas is increased from ${27^ \circ }C$ to ${127^ \circ }C,$ then percentage increase in ${V_{rms}}$ is

A closed compartment containing gas is moving with some acceleration in horizontal direction. Neglect effect of gravity. Then the pressure in the compartment is

The time average of the kinetic energy of one molecule of a gas taken over a long period of time

The kinetic energy per $g\;mol$ for a diatomic gas at room temperature is

One kg of a diatomic gas is at a pressure of $8 imes {10^4}{\rm{\;N}}{{\rm{m}}^{ - 2}}$. The density of the gas is $4\;{\rm{kg}}{{\rm{m}}^{ - 3}}$. What is the energy of the gas due to its thermal motion?
