Density

Vapor Pressure

Specific Gravity

Viscosity

Equation: Density= Mass/Volume

Density is highly variable in gases nearly proportional to the pressure. Density can also be described as how closely and tightly packed the material may be.

Illustration:

Vapor pressure: the pressure at which a liquid boils and is in equilibrium with its own vapor.

Vapor pressure is always dependent on temperature. The higher the temperature goes, higher the vapor pressure

Specific gravity is the ratio of a fluid density to a standard reference fluid, typically water at 4 ̊C (for liquids) and air (for gases):

Equation: SG = (Density of Material) (Density of Water)

Viscosity is a measure of a fluid’s resistance to flow. It determines the fluid strain rate that is generated by a given applied shear stress.

Temperature has a strong and pressure has a moderate effect on viscosity. The viscosity of gases and most liquids increases slowly with pressure.
