Consider the following statements regarding the various measures of atmospheric humidity:
1. Generally Absolute humidity does not change with increase or decrease of temperature, if no additional vapour is added through additional evaporation.
2. Specific humidity is affected by changes in air pressure or air temperature because it is measured in units of weight (grams)
Select the correct answer using the codes given below.
  • a)
    1 only
  • b)
    2 only
  • c)
    Both 1 and 2
  • d)

The option 2 is wrong. Both statements are discussed below:
  • Generally Absolute humidity does not change with increase or decrease of temperature , if no additional vapour is added through additional evaporation, but it changes with contraction (after decent) or expansion (on ascent) of air.
  • Specific humidity is seldom affected by changes in air pressure or air temperature because it is measured in units of weight (grams). It is directly proportional to vapour pressure, which is the partial pressure exerted by water vapour in the air and is independent of other gases and is inversely proportional to air pressure.

Explanation:

Absolute Humidity:
- Absolute humidity refers to the total mass of water vapor present in a unit volume of air.
- It is not affected by changes in temperature if no additional vapor is added through additional evaporation. This is because absolute humidity is a measure of the actual amount of water vapor in the air, regardless of the air's temperature.

Specific Humidity:
- Specific humidity is a measure of the actual mass of water vapor present in a unit mass of air.
- Unlike absolute humidity, specific humidity is affected by changes in air pressure or air temperature because it is measured in units of weight (grams). As air pressure and temperature change, the weight of water vapor in a given mass of air will also change, impacting the specific humidity.
Therefore, the correct answer is option 'A', as only statement 1 is true regarding absolute humidity, while statement 2 is true for specific humidity.
