Question

What is vapour pressure of liquids ? how the vapour pressure of a liquid is related to its boiling point

Answer 1

Answer:

the pressure exerted by the vapour of liquid in equlibrium with its liquid phase at constant temperature is called vapour pressure.

Vapour Pressure is inversely proportional to Boiling Point

Answer 2

The pressure exerted by the vapour molecules on the surface of the liquid when it is in equilibrium with its liquid is called vapour pressure

When a liquid is heated in an open vessel the liquid vaporizers from the surface. At the temperature at which vapour pressure of the liquid becomes equal to external pressure vaporization can occur through out the bulk of the liquid and vapour expands freely into the surroundings

The temperature at which the vapour pressure of a liquid is equal to the atmospheric pressure is called boiling point

At 1 atm pressure boiling temperature is called Normal boiling point

If the pressure is one bar then the boiling point is called standard boiling point of the

Vapour Pressure is inversely proportional to Bioling point
