Given, $1$ mole of $O _2$ at temperature $T$, pressure $P$ and $2$ moles of $H _2$ at a temperature $2 T$
$P_1=\frac{n \times R T}{V}$
$P_0=\frac{R T}{V}=P$
$P_H=\frac{4 R T}{V}=4 P$

Consider a gas with density $\rho $ and $\bar c$ as the root mean square velocity of its molecules contained in a volume. If the system moves as whole with velocity $v,$ then the pressure exerted by the gas is
$1$ mole of rigid diatomic gas performs a work of $Q / 5$ when heat $Q$ is supplied to it. The molar heat capacity of the gas during this transformation is $\frac{ x R }{8},$ The value of $x$ is $\ldots \ldots \ldots .$ $[ K =$ universal gas constant $]$
The specific heat of the mixture of two gases at constant volume is $\frac {13}{6}\,R$ . The ratio of number of moles of first gas to second is $1 : 2$. The respective gases may be
A spherical soap bubble inside an air chamber at pressure $P_0=10^5 Pa$ has a certain radius so that the excess pressure inside the bubble is $\Delta P=144 Pa$. Now, the chamber pressure is reduced to $8 P_0 / 27$ so that the bubble radius and its excess pressure change. In this process, all the temperatures remain unchanged. Assume air to be an ideal gas and the excess pressure $\Delta P$ in both the cases to be much smaller than the chamber pressure. The new excess pressure $\Delta P$ in $Pa$ is
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 ?
$125\, ml$ of gas $A$ at $0.60$ atmosphere and $150\, ml$ of gas $B$ at $0.80$ atmosphere pressure at same temperature is filled in a vessel of $1$ litre volume. What will be the total pressure of mixture at the same temperature ............... $\mathrm{atmosphere}$
