Distinguish between Absolute humidity and Relative humidity.
50m^(3) of saturated vapour is cooled down from 30^(@)C to 20^(@)C .Find the mass of the water condensed. The absolute humidity of saturated water vapour is 30g m^(-3) at 30^(@)C and 16g m^(-3) at 20^(@)C .
If the relative humidity is more than 60%, then then the air is ……….. .
Absolute zero is,
Insstrument to measure humidity ………….
Dry air : less than 60% Relative humidity :: Humind air. …..
If the relative humidity is ………………. 60%, then the air is dry.
At absolute zero, Si acts as
