The table above shows the saturation vapour pressure against temperature in a certain town. If the vapour pressure in this town at 20oC is 10mmHg, what is the relative humidity?
  • A.
    170.0%
  • B.
    57.0%
  • C.
    17.5%
  • D.
    10.0%
Correct Answer: Option B
Explanation

R.H = Partial Pressure of Water Vapour Presentx100_1S.V.P at temperature of atmosphere
= _10x100_117.50
= 57.14%
