WebActivity A: Vapor pressure and boiling point Get the Gizmo ready: Check that No solute is selected. Set the Air temp to 25 °C. Introduction: At the surface of a body of water, water molecules are constantly moving from the liquid phase to the gas phase, and vice versa. The molecules that evaporate collide against the walls of the beaker, creating vapor pressure. WebThe vapor pressure is a measure of the presure (force per unit area) exerted by a gas above a liquid in a sealed container. Vapor pressure is a property of a liquid based on the strength of its intermolecular forces. A liquid with weak intermolecular forces evaporates more easily and has a high vapor pressure. imdb top rated movies 2013

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. WebThis increases our molar volume relative to an ideal gas, which results in a value of Z Z that is greater than 1 1. The error in molar volume gets worse the more compressed the gas becomes, which is why the difference between Z Z for the real and ideal gas increases with pressure.
