What will be the pressure at $0\,^oC$ in Kolkata,Chennai,and Mumbai (in $,bar$)?

At a constant temperature and pressure,the ratio of the densities of two gases is $1 : 16$. The ratio of their rates of diffusion will be ........

For the diffusion of a gas at pressure $P$,the rate of diffusion is expressed by :

Given below are two statements.
Statement $I$: Viscosity of liquid decreases with increase in temperature.
Statement $II$: The units of viscosity are $kg \ m^{-1} \ s^{-2}$.
The correct answer is

$A$ neon-dioxygen mixture contains $64 \ g$ $O_2$ and $160 \ g$ $Ne$. If the total pressure is $25 \ bar$,calculate the partial pressure of dioxygen. (in $bar$)

What is the ratio of kinetic energy of $7 \ g$ of nitrogen and $4 \ g$ of oxygen at $T \ K$?
