Thermodynamics I: How to find density from specific volume?

In thermodynamics, the specific volume of a substance is the ratio of the substance's volume to its mass. It is the reciprocal of density and an intrinsic property of matter as well.

to get density, it is one divided by specific volume

example is 2.008 m³/kg

density is 1 / 2.008 m³/kg = 0.4980 kg/m³

Density = mass ÷ volume 

Example: 1,000kg/m^3 for water 

Specific Volume = volume ÷ mass

Example: 1m^3/1,000kg

The quantities are reciprocal identities.

Specific Volume is used in gases where

Volume is influenced by temperature and 

pressure.

Just look at the units.  If you have m^3/kg and you want kg/m^3, you just take the reciprocal.

Density = 1 / specific volume
