Question

What leads to the lowering of freezing point

  1. Impurities
  2. purity
  3. External forces
  4. None of these

hintHint:

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.
