Question

Solve the following:
(a) When the temperature of the air is 30°
C, its vapour-holding capacity is 30.37
gms/ cu.m. If absolute humidity is 18
gms cu.m. then what would be the
relative humidity?
b) What would be the absolute humidity of
air if 1 cu.m. air contains 4.08 gms of
vapour at 0°C temperature?​

Answer 1

Answer:

Step-by-step explanation:

Just a point that leads many astray the air does not have a “vapour-holding capacity”. Water has a propensity to become vapour that rises with a rise in temperature. Air or no air, the amount of water in the vapour phase depends only in temperature. The exact same amount of water will evaporate at a given temperature no matter the atmospheric pressure.

Relative humidity is the actual amount of water vapour divided by the equilibrium amount x 100%

So. 18/30.37 x 100% = 59% relative humidity.
