Thermodynamics Properties in brief

Thermodynamics properties can be mainly classified as :

1. Intensive Properties
2. Extensive Properties

• Intensive properties are those that are independent of the amount of mass.
• Extensive properties are those that vary directly with the mass.

Specific volume  is the total volume (V) of a substance divided by the
total mass (m) of that substance.

• Density is the total mass (m) of a substance divided by the total
volume (V) occupied by that substance.

• Specific gravity (S.G.) is a measure of the relative density of a substance
as compared to the density of water at a standard temperature.

• Humidity is the amount of moisture (water vapor) in the air. It can be
measured in absolute or relative units.
