Answer 1

A psychrometer measures relative humidity by comparing the temperature of a wet bulb (moistened) and a dry bulb (unenclosed) thermometer. The difference in temperature between these two bulbs is used to determine the moisture content of the air, thereby calculating relative humidity. Therefore, the correct response is:

It compares the temperature in wet air and dry air.
