A gas consisting of a rigid diatomic molecules was initially under standard condition. Then, gas was compressed adiabatically to one$-$fifth of its initial volume. What will be the mean kinetic energy of a rotating molecule in the final state ?
The $r.m.s.$ speed of the molecules of a gas in a vessel is $400$ $m{s^{ - 1}}$. If half of the gas leaks out, at constant temperature, the $r.m.s.$ speed of the remaining molecules will be ..... $ms^{-1}$
A flask contains hydrogen and oxygen in the ratio of $2: 1$ by mass at temperature $27^{\circ} C$. The ratio of average kinetic energy per molecule of hydrogen and oxygen respectively is :
If one mole of the polyatomic gas is having two vibrational modes and $\beta$ is the ratio of molar specific heats for polyatomic gas $\left(\beta=\frac{ C _{ P }}{ C _{ v }}\right)$ then the value of $\beta$ is:
The change in the magnitude of the volume of an ideal gas when a small additional pressure $\Delta P$ is applied at a constant temperature, is the same as the change when the temperature is reduced by a small quantity $\Delta T$ at constant pressure. The initial temperature and pressure of the gas were $300\, K$ and $2\; atm$ respectively. If $|\Delta T|=C|\Delta P|$ then value of $C$ in $(K / a t m)$ is......
