What are some applications of understanding vapor pressure?

An extremely low vapour pressure (e.g. ca. 100 pPa at 298 K for [C4mim][PF6] Citation1 compared with 3 kPa at 298 ... The vapor pressure is a measure of the presure (force per unit area) exerted by a gas above a liquid in a sealed container. The vapour pressure is directly proportional to temperature. This means that as the temperature of a liquid or solid increases its vapour pressure also ... Enthalpies of fusion and melting points obtained using Differential Scanning Calorimetry (DSC) were used to obtain sub-cooled liquid vapour pressures. They have ... Dec 14, 2024 ... Liquid-water temperature controls the rate of evaporation, and humidity (water-vapor concentration in air) controls the rate of condensation. In centrifugal pump technology, vapour pressure refers to the pressure at which the vapour and liquid phases are in equilibrium (see NPSH). The ... As a liquid continues to evaporate into a space above it, the pressure of its vapour increases. A point of equilibrium is reached at which the rate of ... The relative lowering of vapour pressure is defined as the ratio of lowering of vapour pressure to vapour pressure of pure solvent. Aug 25, 2023 ... On wikipedia it says Dimethylmercury has a high vapor pressure so it quickly forms a deadly amount of vapor. So is a high vapor pressure the same as a high ... Dec 15, 2021 ... Note that vapor pressure increases as temperature increases. (3) NPSHR := Net Positive Suction Head Required to avoid cavitation. This quantity ...
