Question

How can boiling point of a liquid be reduced?

Answer 1

The boiling point of a liquid is defined as thetemperature at which the vapor pressure of the liquid is equal to the external pressure. When the pressure above a liquid is reduced, the vapor pressure needed to induce boilingis also reduced, and the boiling point of theliquid decreases.

Answer 2

Boiling point of a liquid decreases by two methods:------

1. By decreasing the conc. Of impurities in the liquid

2. By increasing the temperature of the liquid

3. By decreasing the ambient pressure of the liquid
