  2. Superheated water - Wikipedia

    en.wikipedia.org/wiki/Superheated_water

    Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F). [ citation needed ] It is also known as "subcritical water" or "pressurized hot water".

  3. Superheating - Wikipedia

    en.wikipedia.org/wiki/Superheating

    Video of superheated water in a microwave explosively flash boiling, why it happens, and why it's dangerous. Bloomfield, Louis A. "A series of superheated water with oil film experiments done in the microwave by Louis A. Bloomfield, physics professor at the University of Virginia. Experiment #13 proceeds with surprising violence".

  4. Hydrothermal explosion - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_explosion

    Hydrothermal explosions occur when superheated water trapped below the surface of the Earth rapidly converts from liquid to steam, violently disrupting the confining rock. Boiling water, steam, mud, and rock fragments are ejected over an area of a few meters up to several kilometers in diameter.

  5. Hydrothermal vent - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_vent

    Black smokers are formed in fields hundreds of meters wide when superheated water from below Earth's crust comes through the ocean floor (water may attain temperatures above 400 °C (752 °F)). [1] This water is rich in dissolved minerals from the crust, most notably sulfides. When it comes in contact with cold ocean water, many minerals ...

  6. Superheated steam - Wikipedia

    en.wikipedia.org/wiki/Superheated_steam

    Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...

  7. Saturation dome - Wikipedia

    en.wikipedia.org/wiki/Saturation_Dome

    The temperature will remain constant while it is at constant pressure underneath the saturation dome (boiling water stays at a constant of 212F) until it reaches the saturated vapor line. This line is where the mixture has converted completely to vapor. Further heating of the saturated vapor will result in a superheated vapor state.

  8. Wet oxidation - Wikipedia

    en.wikipedia.org/wiki/Wet_oxidation

    The oxidation reactions occur in superheated water at a temperature above the normal boiling point of water (100 °C), but below the critical point (374 °C). The system must be maintained under pressure to avoid excessive evaporation of water. This is done to control energy consumption due to the latent heat of vaporization. It is also done ...

  9. Frasch process - Wikipedia

    en.wikipedia.org/wiki/Frasch_process

    The Frasch process can be used for deposits 50–800 meters deep. 3-38 cubic meters of superheated water are required to produce every tonne of sulfur, and the associated energy cost is significant. [1] A working demonstration model of the Frasch process suitable for the classroom has been described. [9]
