The relative humidity would be ________% if the actual water vapor in the air was 10 grams per cubic meter, the air's capacity t
lys-0071 [83]

Answer: The Relative humidity is 50%

Explanation: Relative humidity is the ratio of the air’s water vapour content (the actual amount of water vapour in the air) to its water vapour capacity at a given temperature. It depends on temperature and the pressure of the system of interest and it is usually expressed in PERCENTAGE; the higher the percentage, the more humid the air/water mixture.

The formula of Relative humidity (%) = (water vapor content / water vapor capacity) x 100%

Where: Water vapour content is the actual amount of water vapour in the air. Which is 10g/cm³ from the question above;

Water vapour capacity is the air's capacity to hold water vapour. Which is 20g/cm³ from the question above.

Therefore, RH(%)= (10g/cm³ / 20g/cm³) x 100 = 0.5 x 100= 50%

This means that the air contains half of the water vapour it could hold at 20 degree Celsius.
