Q111

Which of the following statements regarding humidity is/are correct ?

  1. It is a ratio between the actual amount of water vapour present in the atmosphere and the maximum amount it can hold at a given temperature.

  2. When the relative humidity is high, more water evaporates from the skin.

  3. Higher the air temperature lower the relative humidity of the air.

Select the answer using the code given below :

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

Solution.

Answer: (c) 1 and 3 only

  1. Statement 1 is correct: it defines relative humidity.
  2. Statement 2 is wrong: when relative humidity is high, less water evaporates from the skin, which is why humid days feel sticky.
  3. Statement 3 is correct: warmer air can hold more water vapour, so the same moisture gives a lower relative humidity.

Trap: Statement 3 assumes the amount of water vapour stays the same; that is the standard reading.
