The vapor pressure of pure water at 25 °C is 23.8 torr. Determine the vapor pressure (torr) of water at 25 °C above a solution prepared by dissolving 35 g of urea (a non-volatile, non-electrolyte, MW = 60.0 g/mol) in 75 g of water.
The water vapor pressure in a water-glycerin system at 25° has been studied. Margules' two-membered equation does not describe the experimental data throughout the range of concentration of glycerin.doi:10.1007/BF00907997A. N. Kirgintsev
The meaning of VAPOR PRESSURE is the pressure exerted by a vapor that is in equilibrium with its solid or liquid form —called also vapor tension.
The Saturation pressure of water vapor in moist air at dry bulb temperature25oCcan be calculated: First, convertion from °C to K: (25 °C) + 273 = 298 (K) Then Eq. (1) is used: pws= e(77.3450 + 0.0057 (298 K) - 7235 / (298 K) )/ 298 [K]8.2 ...

For example, tin has a vapor pressure of 10−2 Torr 1000°C above its melting point. Aluminum and lead have vapor pressures of 10−2 Torr at about 500°C above their melting points. Most elements vaporize as atoms but some, such as Sb, Sn, C, and Se, have a significant portion...
For, the thermal conductivity values for air and water vapor at 25°C are of the same order of magnitude. For instance, the thermal conductivity of air at 25°C is 0.026 Wm− 1 K− 1 and for water vapor, it is 0.020 Wm− 1 K− 1. As a result, the assumption of one comp...
