The term that describes the amount of water vapor in the air is?

• A. Humidity
• B. Density
• C. Temperature
• D. Pressure

Answer: (A)

Humidity is the term for how much water vapor is present in the air. It describes the moisture content of the atmosphere, which can be measured in various ways—relative humidity, the percentage of moisture relative to what the air could hold at that temperature, and absolute humidity, the mass of water vapor per volume of air. The other options describe different properties: density is about mass per volume, temperature is how hot or cold the air is, and pressure is the force per area exerted by the air. None of those directly quantify water vapor content.
