A very tall vertical cylinder is filled with a gas of molar mass $M$ under isothermal conditions at temperature $T.$ The density and pressure of the gas at the base of the container is $\rho_0$ and $p_0$, respectively Choose the correct statement $(s)$ if gravity is assumed to be constant throughout the container
A
Both pressure and density decreases exponentially with height.
BThe variation of pressure is $p = {p_0}e - \frac{{Mgh}}{{RT}}$

The mean free path of molecules of a certain gas at $STP$ is $1500\,d$, where $d$ is the diameter of the gas molecules. While maintaining the standard pressure, the mean free path of the molecules at $373\,K$ is approximately $..........\,d$
The capacity of a vessel is $3$ litres. It contains $6 \,gm$ oxygen, $8\, gm$ nitrogen and $5\, gm$ $C{O_2}$ mixture at $27°C.$ If $R = 8.31\, J/mole$ $ \times $ $kelvin,$ then the pressure in the vessel in $N/{m^2}$ will be (approx.)
For a diatomic gas change in internal energy for unit change in temperature for constant pressure and constant volume is ${U_1}$ and ${U_2}$ respectively. ${U_1}:{U_2}$ is
A gas molecule of mass $M$ at the surface of the Earth has kinetic energy equivalent to $0\,^oC$. If it were to go up straight without colliding with any other molecules, how high it would rise? Assume that the height attained is much less than radius of the earth. ($k_B$ is Boltzmann constant)
$N\,moles$ 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 ?
$14 \,g$ of $CO$ at $27^{\circ} C$ is mixed with $16 g$ of $O _2$ at $47^{\circ} C$. The temperature of mixture is .......... $^{\circ} C$ (vibration mode neglected)
In a thermally isolated system, two boxes filled with an ideal gas are connected by a valve. When the valve is in closed position, states of the box $1$ and $2$ respectively, are ( $1 \,atm , V, T)$ and $(0.5 \,atm , 4 V, T)$. When the valve is opened, then the final pressure of the system is approximately ............... $atm$
