Consider the following pairs. Absolute humidity: the mass of water vap...
The correct answer is option 'C': All three pairs are correct. Let's discuss each pair in detail:
1. Absolute humidity:
Absolute humidity refers to the mass of water vapor present in a given volume of air and water vapor mixture. It is typically measured in grams of water vapor per cubic meter of air. Absolute humidity provides a measure of the actual amount of moisture present in the air.
2. Specific humidity:
Specific humidity is the ratio of the mass of moisture (water vapor) to the total mass of air in a given volume. It is expressed as a fraction or in grams of water vapor per kilogram of air. Specific humidity provides a measure of the actual moisture content in the air, independent of temperature.
3. Relative humidity:
Relative humidity is the ratio of the actual amount of water vapor present in the air to the maximum amount of water vapor that the air can hold at a particular temperature. It is expressed as a percentage. Relative humidity takes into account the temperature-dependent capacity of air to hold moisture.
Explanation:
- Absolute humidity measures the actual mass of water vapor present in the air, regardless of temperature or the air's capacity to hold moisture.
- Specific humidity measures the actual mass of water vapor present in the air per unit mass of air. It provides information about the moisture content independent of temperature.
- Relative humidity, on the other hand, considers both the actual amount of water vapor present and the air's capacity to hold moisture at a given temperature. It helps understand how close the air is to saturation.
In summary, absolute humidity provides the actual mass of water vapor, specific humidity provides the ratio of moisture to air mass, and relative humidity factors in both the actual moisture content and the air's capacity to hold moisture at a specific temperature. Therefore, all three pairs are correct.

Humidity is the amount of moisture in the air around us, and there are three ways to track it. The most common of them is absolute humidity: the mass of water vapour in a given volume of the air and water vapour mixture, expressed as kg/m3. The second is specific humidity, equal to the mass of the moisture divided by the mass of air. It is expressed as a dimensionless number (but sometimes also as grams per kilogram, among other similar units.
The third way is relative humidity: it is important because it factors in the amount of vapour that air can hold at different temperatures.
