Which of the following statement is not correct ?

Viscosity of glycol is greater than that of ethanol

Viscosity of a liquid increases with increase in impurities

Variation of viscosity with temperature is given by n - Ae—BRT

Capillary action of a liquid is due to force of surface tension

The ratio of `u_(av)` and `u_(mp)` is 2 : 3

The unit of van der waals: constant a is `L^(-2)` atm `mol^(-1)`

The mean square speed of a gas varies linearly with kelvin temperature

The increasing order of average, most probable and root mean square speeds is `u_(rms)ltu_(av)ltu_(mp)`

at low pressure the molecules of an ideal gas move with slower speed as compared to the gas at high pressure.

The value of gas constant R is `8.314.JK^(-1) Mol^(-1)`

The value of Boltzmann constant k is `1.38xx10^(-23)JK^(-1) "molecule^(-1)`

The van.der waals constant a is a measure of forces of attraction between gaseous molecules of a gas.
