Question 223General Subjects - 1st Asst/Chief

A) The dry bulb temperature is the correct answer. The dry bulb temperature is the temperature measured by an ordinary thermometer. It represents the actual air temperature, unaffected by the moisture content of the air. This is in contrast to the wet bulb temperature, which measures the cooling effect of evaporation, and the dew point temperature, which represents the temperature at which the air becomes saturated with water vapor. The other options, wet bulb temperature, dew point temperature, and saturation temperature, are related psychrometric properties that require specialized instruments to measure, rather than an ordinary thermometer.
