Question

Humidity means

• A. Pressure difference in atmospheric air
• B. Amount of water vapour in atmospheric air
• C. Temperature in the atmosphere
• D. Quantity of heat energy given by the Sun

Answer 1

The Correct Option is B

Step 1: Understand the concept of humidity.

Humidity refers to the amount of water vapor present in the atmospheric air. It is a measure of how much moisture is in the air at a given time and location.

Step 2: Analyze the options.

• (1) Pressure difference in atmospheric air: Humidity is not related to pressure differences. This option is incorrect.
• (2) Amount of water vapour in atmospheric air: This is the correct definition of humidity.
• (3) Temperature in the atmosphere: Humidity is not directly related to temperature. This option is incorrect.
• (4) Quantity of heat energy given by the Sun: Humidity is unrelated to the Sun's heat energy. This option is incorrect.

Final Answer: Humidity refers to the \( \mathbf{\text{amount of water vapour in atmospheric air}} \), which corresponds to option \( \mathbf{(2)} \).
