What is air density?

Air density is a measure of how much mass is contained in a given volume of air. It is typically expressed in units of kilograms per cubic meter (kg/m^3) or grams per cubic centimeter (g/cm^3). Air density can vary depending on factors such as temperature, pressure, and humidity. Generally, air density decreases with increasing altitude, as the air becomes less dense at higher elevations.

Air density is a measure of the mass of air per unit volume. It is usually expressed in kilograms per cubic meter (kg/m³). Air density varies with temperature, pressure, and humidity. Warm air is less dense than cold air, and moist air is less dense than dry air. The density of air at sea level and 20°C is approximately 1.2 kg/m³.
