Humidity refers to a number of indexes used to quantify the amount of water vapor in a parcel of air (held at a consent temperature and pressure). a. True
b. False

True.

Explanation:

Humidity is the amount of water molecules present in the air at that particular temperature and pressure. As the temperature increases, the air has the ability to hold more water molecules which increases the humidity in the air. The relative humidity is dependent on air temperature. If the water vapor content remains the same and the temperature decreases, the relative humidity increases in the air.
