Regarding humidity consider the following statements: 1. Absolute hum...
Explanation:

Absolute Humidity:
Absolute humidity refers to the actual amount of moisture present in the air, regardless of temperature. It is a measure of the total water vapor content in a given volume of air and is usually expressed in grams per cubic meter (g/m3) or grams per kilogram (g/kg).

Relative Humidity:
Relative humidity is the ratio of the actual amount of moisture present in the air to the maximum amount of moisture the air can hold at a particular temperature. It is expressed as a percentage and provides a measure of how close the air is to saturation. Relative humidity is dependent on both the temperature and the absolute humidity.

Specific Humidity:
Specific humidity is a measure of the actual amount of moisture present in the air on a mass basis. It is the ratio of the mass of water vapor to the total mass of the air parcel. Specific humidity is expressed in grams per kilogram (g/kg) and is not dependent on temperature.

Analysis of the Statements:
1. Absolute humidity is the water content of the air.
This statement is correct. Absolute humidity refers to the actual amount of moisture present in the air.

2. Relative humidity, expressed as a per cent, measures the current absolute humidity relative to the maximum for that temperature.
This statement is correct. Relative humidity is a measure of the current absolute humidity relative to the maximum amount of moisture the air can hold at a particular temperature.

3. Specific humidity is a ratio of the water vapor content of the mixture to the total air content on a mass basis.
This statement is incorrect. Specific humidity is a ratio of the water vapor content of the mixture to the total mass of the air parcel, not the total air content. It is not dependent on temperature.

Conclusion:
Based on the analysis, statement 3 is incorrect, while statements 1 and 2 are correct. Therefore, the correct answer is option 'D' - None of the above.
