The humidity of air measured i percentage is called _

A Absolute humidity
B Specific humidity
C Relative humidity
D All of these

Correct Answer: Relative humidity

Relative humidity is the amount of water vapor present in the air divided by the maximum amount that the air could contain at that temperature. Relative humidity is expressed as a percentage. The relative humidity is 100% if the air is saturated with water vapor and 0% if no water vapor is present in the air at all.
