List of top Physics Questions on kinetic theory asked in BHU UET

Heat absorbed by a mass of 1 g of helium, when its temperature rises from $ 11{}^\circ C $ to $ 131{}^\circ C $ at constant volume, is H. Heat absorbed by 7 g of nitrogen, when its temperature rises from $ 11{}^\circ C $ to $ 71{}^\circ C $ at constant volume, is $ {{H}_{N}} $ . The ratio of H to $ {{H}_{N}} $ is

A closed vessel contains $8\, g$ of oxygen and $7\,g$ of nitrogen. The total pressure is $10$ atm at a given temperature. If now oxygen is absorbed by introducing a suitable absorbent the pressure of the remaining gas (in atm) will be

The speed of sound in hydrogen at NTP is $1270 \,ms$ Then, the speed in a mixture of hydrogen and oxygen in the ratio $4 : 1$ by volume will be

Two vessels $A$ and $B$ having equal volume contain equal masses of hydrogen in $A$ and helium in $B$ at $300 \,K$. Then, mark the correct statement.

The kinetic energy of $1 \,g$ molecule of a gas, at normal temperature and pressure is $( R = 8.31 \,J \, mol^{-1} \, K^{-1} )$
