Vapor Pressure common Liquids

Vapor and saturation pressure for some common liquids

Sponsored Links

The vapor pressure of a liquid is defined as the pressure exerted by the molecules that escapes from the liquid to form a separate vapor phase above the liquid surface.

The pressure exerted by the vapor phase is called the

  • vapor or saturation pressure

Vapor or saturation pressure depends on temperature.

If a fluid consist of more than one component (a solution), components with

  • higher vapor pressure are called light components
  • lower vapor pressure are called heavy components

Temperature and Vapor or Saturation Pressure for some common Fluids

At atmospheric pressure saturation temperature of  

  • water : 100 oC  (212 oF)
  • ethyl alcohol : 78.5 oC (173 oF)

Liquids - Vapor Pressure

Approximate vapor pressure for temperatures in the range 20 oC - 25 oC (68 oF - 77 oF).
