Accepted Answer
The percent increase in the vapor pressure of water is 6.7%.Vapor pressure, or equilibrium vapor pressure, is defined as the pressure exerted by a vapor in thermodynamic equilibrium with the condensed phase at a given temperature in a closed system. Equilibrium vapor pressure is a measure of the evaporation rate of a liquid.The vapor pressure of a liquid is the equilibrium pressure of the vapor relative to that liquid (or solid). That is, the vapor pressure resulting from the evaporation of a liquid (or solid) over a liquid (or solid) sample in a closed container.Vapor pressure is the pressure created by the evaporation of a liquid. Three common factors that affect vapor pressure are surface area, intermolecular forces, and temperature. Molecular vapor pressure varies with temperature.At 14°C Vapour pressure of water = 12 torrAt 15 °C vapour pressure of water = 12.8 torr ΔP = 12.8 - 12 torr = 0.8 torr% increase in vapour pressure = 0.8/12 × 100 = 6.7 %Learn more about vapor pressure here :-https://brainly.com/question/2272852#SPJ4
