Question

Find the incorrect statement about relative humidity
1. Relative humidity increases with the increase in temperature.
2. Relative humidity increases with the increase in water vapour in the air at a constant
3. Relative humidity decreases with the increase in temperature.
4. Relative humidity is measured by Hygrometer

Answer 1

Correct Answer - Option 1 : Relative humidity increases with the increase in temperature.

Option 1 is NOT correct.

• Relative humidity tells us how much water vapor is in the air, compared to how much it could hold at that temperature
• If the relative humidity is 100%, the air is saturated.
• If the relative humidity is 50%, the air contains half the water vapor required for it to be saturated.
• If the amount of water vapor in the air increases, the relative humidity increases, and vice versa.
• If the water vapor content stays the same and the temperature drops, the relative humidity increases.
• If the water vapor content stays the same and the temperature rises, the relative humidity decreases. Hence, Option 1 is NOT correct.
• This is because colder air doesn’t require as much moisture to become saturated as warmer air.
