Most of the real gases behave like an ideal gas at
low pressure and low temperature
high pressure and high temperature
high pressure and low temperature
low pressure and high temperature
At temperature $T, N$ molecules of gas A each having mass $m$ and at the same temperature $2N$ molecules of gas $B$ each having mass $2\,m$ are filled in a container. The mean sqaure velocity of molecules of gas $B$ is $v^2$ and mean square of $x$ component of velocity of molecules of gas$ A$ is $w^2$. The ratio of $w^2/v^2$ is :
The average kinetic energy of hydrogen molecules at $300\, K$ is $E$. At the same temperature, the average kinetic energy of oxygen molecules will be
A gas mixture consists of $2$ moles of $O_2$ and $4$ moles of $A_r$ at temperature $T.$ Neglecting all vibrational modes, the total internal energy of the system is
The graph which represents the variation of mean kinetic energy of molecules with temperature $t^o\ C $ is
The energy of a gas/litre is $300$ joules, then its pressure will be
