Describe what is the vapour pressure? When the temperature is 100 degree Celsius, what is the vapour pressure of water?

Solutions

Expert Solution

Ans:

 

The pressure exerted by vapours of a liquid on the surface of the liquid at equilibrium is the vapour pressure of given liquid. Vapour pressure of a solution containing non volatile solute is always less than the vapour pressure of pure solvent.

 

At hundred degree Celsius, the vapour pressure of water is 760 mm Hg or 1 atmosphere.

 


The pressure exerted by vapours of a liquid on the surface of the liquid at equilibrium is the vapour pressure of given liquid.
