	If the molecular weight of two gases are $M_1$ and $M_1$, then at a temperature the ratio of root mean square velocity v1 and v2 will be
	To what temperature should the hydrogen at 327°C be cooled at constant pressure, so that the root mean square velocity of its molecules become half of its previous value
	At a certain temperature, the r.m.s. velocity for ${{O}_{2}}$ is 400 m/sec. At the same temperature, the r.m.s. velocity for ${{H}_{2}}$ molecules will be
	At a pressure of $24 \times {{10}^{5}}\,dyne/c{{m}^{2}}$, the volume of ${{O}_{2}}$ is 10 litre and mass is 20 gm. The r.m.s. velocity will be
	The r.m.s. velocity will be greater for
	In thermal equilibrium, the average velocity of gas molecules is
	At what temperature will the oxygen molecules have the same root mean square speed as hydrogen molecules at 200 K
	The absolute temperature of a gas is determined by
	The root mean square velocity of the molecules in a sample of helium is 5/7th that of the molecules in a sample of hydrogen. If the temperature of hydrogen sample is 0°C, then the temperature of the helium sample is about
