The vapor pressure of pure benzene is 750.0 torr and the vapor pressure of toluene is 300.0 torr at a certain temperature. You make a solution by pouring “some” benzene with “some” toluene. You then place this solution in a closed container and wait for the vapor to come into equilibrium with the solution. Next, you condense the vapor.
Aug 22, 2016 · The most common unit for vapor pressure is the torr. 1 torr = 1 mm Hg (one millimeter of mercury). Most materials have very low vapor pressures. For example, water has a vapor pressure of approximately 20 torr at room temperature (22 °C = 72 °F). But remember that vapor pressures increase with temperature; water will have a vapor pressure of ...

Vapor pressure is a measurement of how readily a condensed phase forms a vapor at a given temperature. A substance enclosed in a sealed vessel initially at vacuum (no air inside) will quickly fill any empty space with vapor. After the system reaches equilibrium and no more vapor is formed, this vapor pressure can be measured.

Aug 13, 2012 · The vapour pressure of any liquid, crude oil, water, mercury, whatever, depends on its temperature. The vapour pressure you should use for control valve sizing should be given for the operating temperature of that valve. If the operating temperature is say 300 C, or 10 C, then quoting the vapour pressure at 38 C is really no use.
Enter 760 (millimeters of mercury, or 1013 hPa -- units do not matter) as the pressure value and 100 as the boiling point. Now you can calculate its boiling point under any pressure. Type 15 in the second left field and 18 will appear in the second right field.

For example, at 25° C, the vapor pressure of water is 24 mm Hg while that of benzene is 92 mm Hg. The difference in pressure at the same temperature is the result of hydrogen bonding found in water (see Hydrogen Bonding). The vapor pressure of a liquid is temperature dependent meaning that it increases with an increase in temperature.
