Description : When the rate of evaporation of water is zero, the relative humidity of the air is A. 0% B. 100% C. 50% D. unpredictable
Last Answer : ANSWER : B
Description : When the dew point temperature is equal to the air temperature then the relative humidity is A. 0% B. 50% C. 100% D. unpredictable
Description : Water will not be vaporized if – (1) the temperature is 0°C (2) the humidity is 0% (3) the humidity is 100% (4) the temperature is 100°C
Last Answer : (3) the humidity is 100% Explanation: If the relative humidity is 100 percent, water will not evaporate as the air is already saturated with moisture. When relative humidity approaches 100 percent, condensation can occur. The lower the relative humidity, the easier it is for moisture to evaporate.
