A graph between vapour pressure and temperature of few liquids is given below. Study the graph and answer following question. Which of the following statements is not true?

Answer»

Boiling point of a liquid is the temperature at which its vapour pressure becomes equal to atmospheric pressure.
Boiling point of water can be INCREASED by increased the pressure above the atmospheric pressure
If liquid B is HEATED in a closed vessel it will boil at 353 K
Liquid C has higher boilingk point than B due to higher INTERMOLECULAR forces.

Solution :Boiling does not occur when liquid is heated ina closed vessel.
