Question

E. Write a short note on -
a. Vapour pressure
b. Surface tension
c. Viscosity​

Answer 1

The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure.

Explanation:

Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.

Answer 2

Explanation:

in in a kilogram state vapour pressure is transfer into solid to liquid state in the constant temperature
