Question

Fog appearing on a cold winter morning is due to a particular phenomenon. This phenomenon is also responsible for:

• A. Drying up of clothes kept near heater.
• B. Drying up of lakes during summer.
• C. Deposition of water droplets on the outer surface of a glass of cold water.
• D. Steam rising from wet clothes while they are ironed.

Answer 1

The correct option is C Deposition of water droplets on the outer surface of a glass of cold water.

Fog formed during winter morning and deposition of water drops on the outer surface of cold water glass are both due to condensation of water vapour present in the air.
Steam rising from wet clothes while they are ironed is due to evaporation of water.
Evaporation is also responsible for drying up of clothes kept near a heater and drying of lakes during summer.
