Question

What is vapour pressure of a liquid? Explain the effect of temperature on it

Answer 1

"The pressure exerted by vapours when they are in equilibrium with liquid phase is called vapour pressure."

When temperature increases intermolecular forces increases and liquid molecule more easily escape from container hence why vapour pressure increases.

Answer 2

Answer:

Fluid pressure is a measurement of the force per unit area. Fluid pressurecan be caused by gravity, acceleration, or forces in a closed container. ... Therefore to define fluid pressure, we can say that it is the pressure at a point within a fluid arising due to the weight of the fluid.
