    The dish is then closed and heated at high temperature until completely clean, fused silica is produced. Comparison of the initial weight of the substance and that of the fused silica allows the content of silicon in the sample to be determined. A generic evaporator dish. The shape of the evaporating dish encourages evaporation in two ways:

  3. Vacuum fryer - Wikipedia

    en.wikipedia.org/wiki/Vacuum_fryer

    A vacuum fryer is a deep-frying device housed inside a vacuum chamber. With vacuum frying it is easier to maintain natural colors and flavours of the finished product. Due to the lower temperatures applied (approximately 130 °C (266 °F)), the formation of suspected carcinogen acrylamide is significantly lower than in standard atmospheric fryers, where the frying temperature is approximately ...

    Air with forced circulation can be effective enough for situations with high boiling point and low condensation rate. Conversely, low-temperature coolants , such as acetone cooled by dry ice or chilled water with antifreeze additives, can be used for liquids with low boiling point (like dimethyl ether , b.p. −23.6 °C).

  7. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    The main feature of thermodynamic diagrams is the equivalence between the area in the diagram and energy. When air changes pressure and temperature during a process and prescribes a closed curve within the diagram the area enclosed by this curve is proportional to the energy which has been gained or released by the air.
