WebVapor Pressure of Water . Temperature: Pressure: Temperature: Pressure (degrees C) (mmHg) (degrees C) (mmHg) WebThe Clausius-Clapeyron equation gives the approximate relationship between saturation vapor pressure ( es) and temperature in the atmosphere. where the water-vapor gas constant ℜ v is 461 J·K –1 ·kg –1, T0 is 273.15 K, e0 is 0.6113 kPa, and Lv is the latent heat of vaporization, 2.5×10 6 J·kg –1. This results in Lv /ℜ v being ... northern rv melbourne

WebAt 15 degress the vapor pressure of water is 12.8 mm Hg. So that does agree with your intuition. At 15 degrees, the vapor only creates a pressure of 12.8 mmg Hg while at 25 degrees, the vapor creates a pressure of 23.8 mm Hg. Meaning, at 25 degrees, more water vaporizes to create a greater pressure. Comment. WebA piston-cylinder device contains 8 kg of superheated water vapor at 300kPa and 250∘C. Steam is now cooled at constant pressure until 70% of its mass condenses (i.e. the other 30% remains vapor). Determine: a) The boundary work b) The heat transfer for this process. c) Plot the P-v diagram (include the pressure, temperature and volume)3. WebProblem #4: At 29.6 °C, pure water has a vapor pressure of 31.1 torr. A solution is prepared by adding 86.8 g of "Y", a nonvolatile non-electrolyte to 350. g of water. The vapor pressure of the resulting solution is 28.6 torr. Calculate the molar mass of Y. Solution: 1) Use Raoult's Law to determine mole fraction of the solvent: northern ryder gang
