Q105

Condensation of water vapour into water is influenced by which of the following factor/factors ?

  1. Volume of air

  2. Humidity

  3. Temperature

Select the answer using the code given below :

  1. (a) 1 only
  2. (b) 1 and 2 only
  3. (c) 2 and 3 only
  4. (d) 1, 2 and 3Correct answer

Solution.

Answer: (d) 1, 2 and 3

  1. Condensation occurs when air reaches saturation.
  2. Temperature affects the saturation vapour pressure, humidity measures how close the air is to saturation, and a change in air volume changes vapour concentration and can cause cooling during expansion.
  3. All three can therefore influence condensation.
