WebRelative humidity is a term commonly used to describe how much water vapor is in the air as a percent. Saturated air is at 100% relative humidity (RH). Air with a 50% RH and 100°F contains half the water vapor of saturated air at 100% RH and 100°F. Enthalpy describes the heat energy content (BTU/lb dry air) of the air and water vapor mixture.

WebIndoors however, 41°F would be very uncomfortable, so we would warm it up. When the outdoor air is heated up to 73°F indoors, the absolute amount of water in the air is still the same. But since warmer air can hold more water, the relative humidity goes down to 33%. On the other hand, warm air can handle more moisture than cooler air.
