The gas with the highest critical temperature is

Which of the following property of water be used to explain the spherical shape of rain droplets?

The SI unit of viscosity coefficient $(\eta)$ is

The maximum number of molecules is present in :

A certain sample of a gas has a volume of 0.2 litre measured at 1 atm pressure and $0^\circ C$. At the o same pressure but $273^\circ C$, its volume will be :

A gas deviates from ideal behavior at a high pressure because its molecules:

The pressure exerted by 1 mole of methane in a 0.25 litre container at 300 K using van der Waals equation (given a = 2.253 $\text{atm L}^2\text{ mol}^{-2}$, b = 0.0428 L $\text{ mol}^{-1}$ ) is

To what temperature must a neon gas sample be heated to double its pressure, if the initial volume of a gas at $75^\circ C$ is decreased by 15%?

Which pair of the gases diffuses with the same rate at same temperature and pressure?
