Question

If the relative humidity of atmosphere air is 100% the rate of evaporation of water will be

Answer 1

Answer:

zero

Explanation:

coz we know humid is related to water....if the humidity is 100 percent then how the water can vapourize...then the ans will zero right

Answer 2

If the relative humidity of atmospheric air is 100%, the rate of evaporation of water will be zero.

Relative humidity:

• The relative humidity of the air is simply referred to as the amount of water content (humidity) in atmospheric air.
• The amount of water vapor in the air is compared to the total amount of air that can exist at current temperature.
• It is represented in percent.

Relative humidity can be calculated using a formula,

Relative humidity  $=$ partial pressure $/$ vapour pressure × 100 %

This can be explained in three cases,

Assume partial pressure as p and vapour pressure as v.

Case 1: When p$<$v, then the temperature is high and relative humidity is low. this is called evaporation.

Case 2: When p$=$v, then the temperature and relative humidity is equal. This is called Saturation.

Case 3: When p$>$v, then the temperature is low and relative humidity is high. this is called condensation. Here, the rate of evaporation is zero.
