Modify access date.The density of humid air varies with water content and temperature. When the temperature increases a higher molecular motion results in expansion of volume and a decrease of density. The density of a gas, dry air, water vapor - or a mixture of dry air and water vapor like moist or humid air - can be calculated with the Ideal Gas Law.

The amount of water vapor in air influence density. Water vapor is relatively light compared to diatomic Oxygen and diatomic Nitrogen - the dominant components in air. When vapor content increases in moist air the amount of Oxygen and Nitrogen are decreased per unit volume and the density of the mix decreases since the mass is decreasing.

Based on specific volume of moist air the moist air density can be calculated. As we can see from 6 - increased moisture content reduces the density of moist air - dry air is more dense than moist air.

Scientific Online Calculator.Follow the links below to get values for the listed properties of air at varying pressure and temperature :.

Air is a mixture of gases at standard conditions. However, at low temperature and high pressures the gas mixture becomes a liquid. The phase diagram for air shows the phase behavior with changes in temperature and pressure. The curve between the triple point and the critical point shows the air boiling point with changes in pressure.

At the critical point there is no change of state when pressure is increased or if heat is added. The triple point of a substance is the temperature and pressure at which the three phases gas, liquid, and solid of that substance coexist in thermodynamic equilibrium. Example - Mass of Air at Temperature o C. From the table above - the density of air is 0. The mass of 10 m 3 air can be calculated as. An air balloon with volume 10 m 3 is heated to o C. The temperature of the surrounding air is 20 o C.

The change in gravity force weight of the air volume is the potential lifting force of the balloon.
