THERMODYNAMIC PROPERTIES
Summary
The important information from this chapter is summarized below.
Thermodynamic Properties Summary
The following properties were defined:
•
Specific volume (n) is the total volume (V) of a substance divided by the
total mass (m) of that substance.
•
Density (r) 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.
The following classifications of thermodynamic properties were described:
•
Intensive properties are those that are independent of the amount of mass.
•
Extensive properties are those that vary directly with the mass.
