d $PV = RT$
$\Rightarrow$ $\frac{{PV}}{T} = R \approx 2 \frac{{cal}}{{mol{\rm{ - }}K}}$

Pressure versus temperature graph of an ideal gas at constant volume $V$ of an ideal gas is shown by the straight line $A$. Now mass of the gas is doubled and the volume is halved, then the corresponding pressure versus temperature graph will be shown by the line
The average kinetic energy of a gas at $-23°C$ and $75\, cm$ pressure is $5 \times {10^{ - 14}}\,erg$ for ${H_2}$. The mean kinetic energy of the ${O_2}$ at $227°C$ and $150\, cm$ pressure will be
A gas at absolute temperature $300\,K$ has pressure $= 4 \times 10^{-10}\,N /m^2$ . Boltzmann constant, $k = 1.38 \times 10^{-23}\,J / K$ . The number of molecules per $cm^3$ is of the order of
Two gases-argon (atomic radius $0.07 \;\mathrm{nm}$,atomic weight $40$ ) and xenon (atomic radius $0.1\; \mathrm{nm},$ atomic weight $140$ ) have the same number density and are at the same temperature. The raito of their respective mean free times is closest to
For a certain process, pressure of diatomic gas varies according to the relation $P = aV^2$, where $a$ is constant. What is the molar heat capacity of the gas for this process?
$N\,moles$ of a diatomic gas in a cylinder are at a temperature $T$. Heat is supplied to the cylinder such that the temperature remains constant but $n\,moles$ of the diatomic gas get converted into monoatomic gas. What is the change in the total kinetic energy of the gas ?
