Question

For saturated air, which of the following correctly describes the relationship among dry-bulb temperature, wet-bulb temperature, and dew-point temperature?

A Wet bulb temperature > Dry bulb temperature > Dew point temperature
B Dry bulb temperature = Wet bulb temperature = Dew point temperature
C Dry bulb temperature > Dew point temperature > Wet bulb temperature
D Wet bulb temperature > Dew point temperature > Dry bulb temperature

Explanation

At 100% relative humidity, the air is saturated: the wet-bulb temperature cannot be lowered by evaporation, and the dew-point temperature equals the actual air temperature. Thus, dry-bulb, wet-bulb, and dew-point temperatures are all equal.
