Question

How can the boiling point of a liquid be raised, without adding any impurity?

Answer 1

Boiling point: It is the temperature at which a liquid gets converted into its corresponding vapours at normal atmospheric pressure.

• The boiling point of a liquid can be raised, without adding any impurity by increasing the pressure around the liquid.
• When pressure is increased, the boiling of the liquid is delayed and this elevates the boiling point.
• By increasing the pressure, the liquid's boiling point can be increased without adding any soluble impurities.
