A psychrometer measures relative humidity by comparing the temperature of a wet bulb and a dry bulb. The dry bulb measures the air temperature, while the wet bulb is cooled by the evaporation of water. The difference in temperatures is used to calculate the relative humidity of the air.
Therefore, the correct response would be: It compares the temperature in wet air and dry air.
It compares the temperature in wet air and dry air.
