Water will not be vapourised if
A). The temperature is 0°C
B). The humidity is 0%
C). The humidity is 100%
D). The temperature is 100°C
The humidity is 100%
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.
