Answer 2

Answer:

Relative humidity is defined as the ratio of the amount of water vapour in the air to the amount the air can hold at the temperature. ... This ratio is expressed in percentage. If the air at 15-degree temperature contains 5 grams of water vapour per kilogram, the relative humidity will be expressed as 5/10 or 50 percent.
