This salt can be taken out from the kettle.In this way,  salt water mixture has been separated into salt and water by the process of distillation. Group I : hazardous area electrical equipment intended for use in the underground parts of mines, and to those parts of surface installations of such mines, likely to become endangered by firedamp and/or combustible dust. (v) Bark protects the attack of fungi and insects, against loss of water by evaporation and against variation of external temperature and loss of water due to evaporation. Bei einer Verdunstung geht ein Stoff vom flüssigen in den gasförmigen Zustand über, ohne dabei die Siedetemperatur zu erreichen. (1) The process of condensation is involved in the formation of clouds in the sky and bringing back water to the surface of earth (in the form of rain, etc.). Your email address will not be published. Water falls from the sky in the form of rain (or if it's cold, sleet, hail or snow). The water present in wet clothes seems to disappear.

It involves no change in the temperature of the steam/water mixture, and all the energy is used to change the state from liquid (water) to vapour (saturated steam). Water present in wet clothes evaporates by receiving heat from the sun (or surrounding air) to form water vapour. In order to recover both salt as well as water from salt water mixture the process of distillation is used. The dissolved substance is left as a solid residue when all the water has evaporated. Wind assists evaporation; for example in clothes dry faster under a fan. 2. Group II :hazardous area electrical equipment intended for use in other places likely to become endangered by explosive atmospheres (surface industries). Evaporation is … Condensation DEFINE. Students and parents can download free a collection of all study material issued by various best schools in India. Vapor-compression refrigeration uses evaporative cooling, but the evaporated vapor is within a sealed system, and is then compressed ready to evaporate again, using energy to do so.
