Apr 24, 2021 · Vapor pressure (or vapour pressure) is the equilibrium pressure of a vapor above its liquid or solid state in a closed container. In this type of closed system, some molecules of a liquid or solid have enough kinetic energy to escape at the surface and enter the vapor (gas) phase.
Apr 12, 2023 · The vapor pressure of liquid nickel at 1606°C is 0.100 torr, whereas at 1805°C, its vapor pressure is 1.000 torr. At what temperature does the liquid have a vapor pressure of 2.500 torr? Answer: 1896°C
Mar 13, 2023 · Vapor pressure is the pressure inside a closed container when a liquid is in equilibrium with its own gas phase so the rate of evaporation is equal to the rate of condensation. When a non-volatile solute is dissolved in a volatile solvent, the vapor pressure of the solvent is reduced.
Jul 13, 2017 · Vapor Pressure Worksheet Vapor pressure curves of several liquids Vapor pressure (y-axis) is shown as a function of temperature for several liquids. For all, the vapor pressure increases with temperature. Shown are: (a) carbon disulfide, CS 2; (b) methanol, CH 3OH; (c) ethanol, CH 3CH 2OH; (d) water, H 2O; (e) aniline, C 6H 5NH 2.
When water evaporates, it changes from a liquid to a gas (water vapor). Water vapor takes up more space than an equal mass of liquid water. As a result, in a closed container, the vapor that forms can exert a significant amount of pressure. This pressure is known as vapor pressure.
