Question

Name the factors that affect the boiling point of a liquid.

Answer 1

Boiling point depends on -

1. Pressure: Boiling point depends on pressure. It increases with increase in atmospheric pressure and decreases with decrease in atmospheric pressure.
2. Impurities: Boiling point also depends on impurities present in liquid. It increases if liquid contains any impurity.

Thus the boiling point of a liquid depends on pressure and impurity.
