Evaporation and precipitation of gypsum GYPSUM PRECIPITATION UPON EVAPORATION If water evaporates and solutes are concentrated so much that a mineral precipitates, the concentrations become fixed if the concentration ratios in solution are
Bavarder sur InternetIn the high-temperature and low water vapor pressure region, gypsum dehydrates to form γ-CaSO 4 in a single-step process (CaSO 4 2H 2 O → γ-CaSO 4); with increasing
Bavarder sur InternetA model is presented that describes the heat transfer through a gypsum wallboard partition assembly incorporating the mass transport effects of water in liquid and vapor form.
Bavarder sur InternetGypsum is moderately water-soluble (~2.0–2.5 g/L at 25 °C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures. When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate (bassanite, often simply called "plaster") and, if heated further, to anhydrous calcium sulfate (anhydrite). As with anhydrite, the
Bavarder sur InternetIncrease the surface area by placing the water in a shallow tray. Blow (preferably warm) air over it by creating a cross-draught or using a fan. (Warmer air holds more moisture.)
Bavarder sur InternetThe heat of vaporization diminishes with increasing temperature and it vanishes completely at a certain point called the critical temperature (Critical temperature for water: 373.946
Bavarder sur Internet1 天前 Visible light can help water evaporate due to the heat it imparts ( SN: 3/8/16 ). But until now, it wasn’t thought to directly break the bonds between water molecules. In the
