A humidity measure that remains constant as temperature and pressure change, and which is expressed as a mass of water vapor per mass (g/kg) of air, is
A) specific humidity.
B) vapor pressure.
C) relative humidity.
D) the dew-point.

Question

Quizplus · Accepted Answer

Specific humidity is the measure of the mass of water vapor per mass of air, and it does not vary with changes in temperature and pressure. Vapor pressure and relative humidity are dependent on temperature and pressure, and the dew-point is the temperature at which the air becomes saturated with water vapor.
