At what temperature is the root mean square velocity of gaseous hydrogen molecules equal to that of oxygen molecules at 47^o C?

When temperature of an ideal gas is increased from 27^o C to 227^o C, its rms speed changed from 400 ms^–1 to V_s. The V_s is

The rms speed of the molecules of a gas at a pressure 10⁵ Pa and temperature 0^o C is 0.5 km/s. If the pressure is kept constant but temperature is raised to 819^o C, the rms speed becomes

The root mean square velocity of a gas molecule of mass m at a given temperature is proportional to

The ratio of the vapour densities of two gases at a given temperature is 9:8, The ratio of the rms velocities of their molecule is

For a gas, the rms speed at 800 K is

The temperature of an ideal gas is increased from 27^o C to 927^o C. The root mean square speed of its molecules becomes

At a given temperature the root mean square velocities of Oxygen and hydrogen molecules are in the ratio

If mass of He atom is 4 times that of hydrogen atom, then rms speed of the is

At temperature T, the rms speed of helium molecules is the same as rms speed of hydrogen molecules at normal temperature and pressure. The value of T is
