When a given amount of air is cooled
|
|
its absolute humidity decreases

|
|
|
its absolute humidity increases
|
|
|
its relative humidity remains constant
|
Explanation:
Detailed explanation-1: -When a given amount of air is cooled the amount of moisture it can hold decreases. If you increase the temperature, however, the amount of water vapor the air can hold increases, so the relative humidity decreases.
Detailed explanation-2: -As you increase air temperature, the ability of the air to hold water vapor increases at an increasing rate.
Detailed explanation-3: -The capacity of the air to hold water vapour does not decrease as the temperature decreases.
