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).
