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.

WebThe saturation vapor pressure is the partial pressure of the water vapor in equilibrium with a plane surface of pure water.
