The gas having average speed four times as that SO₂ (molecular mass 64) is
The temperature of a given mass is increased from 27°C to 327°C. The rms velocity of the molecules increases
The ratio of the vapour densities of two gases at a given temperature is 9: 8. The ratio of the rms velocities of their molecules is
The root mean square velocity of gas molecules is 10km/s. The gas is heated till its pressure becomes four times. The velocity of gas molecules will be
Assertion: The root mean square and most probable speeds of the molecules in a gas are the same. Reason: The Maxwell distribution for the speed of molecules in a gas is symmetrical.
A gas storage tank has a small leak. The pressure in the tank drop more quickly if the gas is hydrogen than if it is oxygen. Why?
