Question

The capacity of the air to hold water vapor: Group of answer choices 1. decreases with an increase in temperature.2. increases with a decrease in temperature.3. increases with an increase in temperature.4. increases with an increase in pressure.

Answer 1

Option (3)

Step-by-step explanation:

The capacity of air to hold moisture or water content is directly proportional to the temperature of the air. This means that, with the increasing temperature, the air is capable of holding more amount of water. This results in a decreasing amount of relative humidity. When the temperature of the air increases and the water vapor content increases simultaneously, it slowly starts to condense and thereby leads to the occurrence of precipitation.

Thus, the correct answer is option (3).

Answer 2

3. increases with an increase in temperature.

Step-by-step explanation:

The air more water vapor at higher temperatures because at higher temperatures the air expands and the inter-molecular space increases so the room for water molecules increases.

Warm air keeps the water molecules warm and prevents them from condensing.

The air can hold the moisture only upto its saturation quantity after which the precipitation occurs in the form of rain, snow, hail, sleet etc.
