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 occupy two containers $A$ and $B$ the gas in $A$, of volume $0.10\,m ^3$, exerts a pressure of $1.40\,MPa$ and that in $B$ of volume $0.15 m ^3$ exerts a pressure $0.7\,MPa$. The two containers are united by a tube of negligible volume and the gases are allowed to intermingle. Then if the temperature remains constant, the final pressure in the container will be (in MPa)
Initially a gas of diatomic molecules is contained in a cylinder of volume $V _{1}$ at a pressure $P_{1}$ and temperature $250\, K$. Assuming that $25 \%$ of the molecules get dissociated causing a change in number of moles. The pressure of the resulting gas at temperature $2000\, K ,$ when contained in a volume $2 V _{1}$ is given by $P _{2}$. The ratio $\frac{P _{2}}{ P _{1}}$ is.
At a pressure of $24 \times {10^5}\,dyne/c{m^2}$, the volume of ${O_2}$ is $10\, litre$ and mass is $20\, gm.$ The $r.m.s.$ velocity will be....... $m/sec$
Two ideal polyatomic gases at temperatures $T _{1}$ and $T _{2}$ are mixed so that there is no loss of energy. If $F _{1}$ and $F _{2}, m _{1}$ and $m _{2}, n _{1}$ and $n _{2}$ be the degrees of freedom, masses, number of molecules of the first and second gas respectively, the temperature of mixture of these two gases is
