The specific heats, $C_P$ and $C_V$ of a gas of diatomic molecules, $A$, are given (in units of $J\, mol^{-1}\, K^{-1}$) by $29$ and $22$, respectively. Another gas of diatomic molecules $B$, has the corresponding values $30$ and $21$. If they are treated as ideal gases, then
One mole of an ideal monatomic gas undergoes a process described by the equation $PV^3 =$ constant. The heat capacity of the gas during this process is
Three closed vessels $A, B$ and $C$ are at the same temperature $T$ and contain gases which obey the Maxwellian distribution of velocities. Vessel $A$ contains only ${O_2},\,B$ only ${N_2}$ and $C$ a mixture of equal quantities of ${O_2}$ and ${N_2}$. If the average speed of the ${O_2}$ molecules in vessel A is ${V_1}$, that of the ${N_2}$ molecules in vessel B is ${V_2}$, the average speed of the ${O_2}$ molecules in vessel $C$ is
A mixture of one mole of monoatomic gas and one mole of a diatomic gas (rigid) are kept at room temperature $\left(27^{\circ} \mathrm{C}\right)$. The ratio of specific heat of gases at constant volume respectively is:
Graph between volume and temperature for a gas is shown in figure. If $\alpha$ = Volume coefficient of gas = $\frac{1}{273}$ per $^o C$,then what is the volume of gas at a temperature of $819 ^o C$
A cylindrical container of volume $4.0 \times 10^{-3} \,{m}^{3}$ contains one mole of hydrogen and two moles of carbon dioxide. Assume the temperature of the mixture is $400 \,{K}$ The pressure of the mixture of gases is:
[Take gas constant as $8.3\, {J} {mol}^{-1} {K}^{-1}$]
Nitrogen gas is at $300^{\circ} C$ temperature. The temperature (in $K$) at which the $rms$ speed of a $H _{2}$, molecule would be equal to the $rms$ speed of a nitrogen molecule, is........
