To which of the following gaseous mixtures is Dalton's law of partial pressures not applicable?

The rate of diffusion of a gas is inversely proportional to

The units of surface tension and viscosity of liquids respectively are

Arrange the states of matter (solid,liquid,and gas) in increasing order of their energy.

$A$ mixture of one mole each of $H_2$,$He$ and $O_2$ are enclosed in a cylinder of volume $V$ at temperature $T$. If the partial pressure of $H_2$ is $2 \ atm$,the total pressure of the gases in the cylinder is $....... \ atm$

The ratio of the rate of diffusion of helium and methane under identical conditions of pressure and temperature will be
