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

The SI unit of viscosity coefficient $(\eta )(\backslash eta)$ 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 $0^{\circ }C0^\backslash circ\; C$. At the o same pressure but ${273}^{\circ }C273^\backslash circ\; C$, 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 ${\text{atm L}}^2{\text{ mol}}^{-2}\backslash text\{atm\; L\}^2\backslash text\{\; mol\}^\{-2\}$, b = 0.0428 L ${\text{ mol}}^{-1}\backslash text\{\; mol\}^\{-1\}$ ) is

To what temperature must a neon gas sample be heated to double its pressure, if the initial volume of a gas at ${75}^{\circ }C75^\backslash circ\; C$ is decreased by 15%?

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