Question

Quizplus · Accepted Answer

When temperatures are below freezing, if the air becomes saturated, the water vapor in the air will directly change into ice without first forming liquid droplets - this is known as the frost point. Dew-point refers to the temperature at which air becomes saturated and water vapor in the air condenses into liquid droplets (dew). Absolute humidity refers to the actual amount of water vapor in the air. Relative humidity is the ratio of the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at a given temperature.
