Differentiate between Absolute Humidity and Relative Humidity.
| Absolute Humidity | Relative Humidity |
|---|---|
| It is the actual amount of water vapour present in the air. | Relative humidity is the ratio between the actual amount of water vapour present in the air and the maximum amount of water vapour the air can hold at that temperature. |
| It does not take temperature into consideration. | It takes temperature into consideration. |
| It is expressed as grams per cubic metre. | It is expressed as a percentage. |
| It does not give us a very good idea of the level of humidity present in the atmosphere as it does not tell us the amount of water which the air needs to become saturated. | It is gives us a fair idea of the humidity of the air. |
