Question
What leads to the lowering of freezing point
- Impurities
- purity
- External forces
- None of these
Hint:
Lowering of vapour pressure.
The correct answer is: Impurities
- The particular temperature at which liquid freezes into solid is called the freezing point.
- Presence of impurities lowers the vapour pressure since the concentration of the solution is increased.
- Hence, presence of impurities lowers the freezing point.
