When a gas is moving, it is convenient to use the density of a gas, which is the mass divided by the volume the gas occupies. The sea level standard value of air density r is ... When working with a static or unmoving gas, it is more convenient to use specific volume, which is the volume divided by the mass.

A closer examination of the definition for specific volume shows that the specific volume v is the inverse of the gas density r ... Either the specific volume or the density can be used in defining the state of the gas using only intensive variables. For many fluid dynamic (moving) applications, the mass varies from...

Molecular weights for acetylene, air, ammonia, argon, carbon dioxide, carbon monoxide, chlorine, hydrogen, natural gas, nitrogen, oxygen, propane and steam are all provided. ... The Gas Density and Specific Volume Calculator calculates the density and specific volume of gas based on a modified version of the Ideal Gas Law:

The specific volume of air is basically the reciprocal of Air Density. As the temperature of the air increases, its density will decrease as its molecules vibrate more and take up more space (as per Boyles law).
