D) partial humidity.

Question

Quizplus · Accepted Answer

The given definition is of relative humidity, which is expressed as a percentage. Absolute humidity refers to the actual amount of water vapor present in the air, regardless of its holding capacity. Dew point refers to the temperature at which the air becomes saturated with water vapor, leading to the formation of dew or fog. Partial humidity is not a valid term in meteorology or atmospheric science.
