Vapor Pressure of Water Marcet Boiler

If energy is added to water, molecule activities will increase and some of the molecules will escape from the surface of the liquid. This process will continue until a state of equilibrium is reached. This state depends on the pressure of the pure material adjacent to water; the less the pressure is, the more easily the molecules leave the liquid surface, needing less energy to come to balance. This unit is consisted of a constant-volume container which is filled with water. The container is then heated so that the constant-volume phase change from water to steam is achieved. During this process, water and steam phases will be continuously adjacent. By using installed measurement instru-ments, pressure and temprature can be measured at any moment.
