See spelling differences or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases solid or liquid at a given temperature in a closed system the equilibrium vapor pressure is an indication of a liquid s evaporation rate. Mb in of hg mm hg. It relates to the tendency of particles to.

A the vapor pressure curve of water intersects the p 1000 mmhg line at about 110 c. Pressure degrees c mmhg degrees c mmhg. Assume we want to calculate the vapor pressure of water in 86 f 30 c. 1 torr 1 mm hg one millimeter of mercury.

But remember that vapor pressures increase with temperature. P 10 a b c t where. The most often used is the antoine equation 4 232 kpa but the buck formula 4 245 kpa is usually the most accurate one for temperature ranges we typically look for. Enter a temperature or a dewpoint or both.

Vapor pressure of water. The vapor pressure of water calculator found the pressure according to five formulas. Vapor pressure of water t. For example water has a vapor pressure of approximately 20 torr at room temperature 22 c 72 f.

The most common unit for vapor pressure is the torr. Antoine constants for water when water temperature in the range of 1 100 celsius a 8 07131 b 1730 63 c 233 426. Most materials have very low vapor pressures. The temperature of the solution is 25 c and the vapor pressures of each of these chemicals at 25 c is 95 1 mm hg for benzene 28 4 mm hg for toluene.
