Question

Quizplus · Accepted Answer

Relative humidity is affected by changes in temperature and pressure. An increase in temperature causes an increase in the amount of moisture that the air can hold, which decreases relative humidity. A decrease in temperature has the opposite effect. Changes in pressure also affect relative humidity, as air masses can expand and contract in response to changes in pressure, which alters the amount of water vapor they contain.
