The work done in an adiabatic change in an ideal gas depends upon only :

The ratio of vapour densities of two gases at the same temperature is $ \frac{4}{25} $, then the ratio of r.m.s. velocities will be :

The kinetic energy of translation of the molecules in 50 g of $ \text{CO}_2 $ gas at 17°C is :

For a particular ideal gas which of the following graphs represents the variation of mean squared velocity of the gas molecules with temperature?
