  2. Superheating - Wikipedia

    en.wikipedia.org/wiki/Superheating

    Below that temperature, a water vapor bubble will shrink and vanish. Superheating is an exception to this simple rule; a liquid is sometimes observed not to boil even though its vapor pressure does exceed the ambient pressure. The cause is an additional force, the surface tension, which suppresses the growth of bubbles. [4] Surface tension ...

  3. 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 ...

  4. Bumping (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Bumping_(chemistry)

    The hardest part of bubble formation is the initial formation of the bubble; once a bubble has formed, it can grow quickly. Because the liquid is typically above its boiling point, when the liquid finally starts to boil, a large vapor bubble is formed that pushes the liquid out of the test tube, typically at high speed.

  5. Superheated water - Wikipedia

    en.wikipedia.org/wiki/Superheated_water

    Water is a polar molecule, where the centers of positive and negative charge are separated; so molecules will align with an electric field.The extensive hydrogen bonded network in water tends to oppose this alignment, and the degree of alignment is measured by the relative permittivity.

  6. Superheater - Wikipedia

    en.wikipedia.org/wiki/Superheater

    A radiant superheater is placed directly in the radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. A convection superheater is located in the convective zone of the furnace, in the path of the hot flue gases, usually ahead of an economizer.

  7. Explosive boiling - Wikipedia

    en.wikipedia.org/wiki/Explosive_boiling

    The rate of bubble nucleation and vapor sphere growth rate increases exponentially closer to the critical temperature. The increasing nucleation prevents the system from going to the spinodal. When the bubble radius reaches the critical size it continues to expand and eventually explodes resulting a mixture of gas and droplets which is termed ...

    This can lead to a dangerous feedback cycle in parts of the world where transpiration is a major source of water vapor that becomes precipitation, such as the Amazon rainforest: as drought ...

  9. Bubble point - Wikipedia

    en.wikipedia.org/wiki/Bubble_point

    In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed when heating a liquid consisting of two or more components. [ 1 ] [ 2 ] Given that vapor will probably have a different composition than the liquid, the bubble point (along with the dew point ) at different compositions are ...
