Relative humidity usually is highest right before sunrise. Why does this occur?
is humidity same as dew point?
Comparing 1 m3 of air with 100% relative humidity at 0°C and 1 m3 of the air with 100% relative humidity at 30°C, choose the correct statement.
Group of answer choices
They both have the same amount of water.
They both have the same absolute humidity.
The air at 0°C has more water in it.
The air at 30°C has more water in it.
