Question

The capacity of the air to hold water vapour _______.

• A. Increases as the temperature increases
• B. Decreases as the temperature increases
• C. Increases as the temperature decreases
• D. Decreases as the temperature decreases

Answer 1

The correct option is A Increases as the temperature increases

Increases as the temperature increases,

The water-vapor content of the atmosphere varies from place to place and from time to time because the moisture-holding capacity of air is determined by temperature. At 30 °C (86 °F), for example, a volume of air can contain up to 4 percent water vapour. At -40 °C (-40 °F), however, it can hold no more than 0.2 percent. The more the temperature more is the water holding capacity.
