Why is moist air less dense than dry air at the same temperature?
How do these factors affect the behavior of aircraft?
Aircraft rely on air density for lift, so changes in air density due to changes in temperature, pressure, or altitude can affect aircraft performance. For example, on hot days when the air is less dense, airplanes need to travel faster to generate the same amount of lift as they would on cooler days with denser air.
