Hint :The molecules cannot escape when a solid or a liquid evaporates to a gas in a closed container. Eventually, some of the gas molecules will collide with the condensed phase and condense back into it. The amount of gas, liquid, and/or solid does not change when the rate of condensation of the gas equals the rate of evaporation of the liquid or solid. The liquid or solid in the container is in equilibrium with the gas in the container.
Complete Step By Step Answer:
The pressure exerted by a vapour in thermodynamic equilibrium with its condensed phases (solid or liquid) at a particular temperature in a closed system is known as vapour pressure. The evaporation rate of a liquid is determined by the equilibrium vapour pressure. It has to do with particles' proclivity for escaping from liquids (or a solid). Volatile refers to a material that has a high vapour pressure at room temperature. Vapor pressure is the pressure exerted by vapour existing above a liquid surface.
The pressure within Earth's atmosphere, commonly known as atmospheric pressure or barometric pressure, is called atmospheric pressure. The standard atmosphere is a pressure unit defined as 101,325 Pa, which is equivalent to 760 millimetres of mercury, 29.9212 inches of mercury, or 14.696 pounds of pressure. The atm unit roughly corresponds to the Earth's mean sea-level atmospheric pressure; that is, the atmospheric pressure at sea level is about 1 atm.
Because we disregard the intermolecular interactions in perfect vapours, the vapour pressure is scarcely affected by atmospheric pressure in an ideal situation. In the event of a genuine gas, however, we would consider the impact of the vapour pressure because we would enable the surrounding atmospheric gases to interact with the vapours above the liquid. We, on the other hand, are blind to such impacts.
Note :
When the temperature of a liquid rises, so does the kinetic energy of its molecules. The number of molecules transitioning into a vapour rises as the kinetic energy of the molecules increases, raising the vapour pressure. According to the Clausius–Clapeyron relationship, the vapour pressure of any material rises non-linearly with temperature. The temperature at which the vapour pressure matches the ambient air pressure is known as the atmospheric pressure boiling point of a liquid.
