  2. 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 ...

  3. Water vapor - Wikipedia

    en.wikipedia.org/wiki/Water_vapor

    The red line on the chart to the right is the maximum concentration of water vapor expected for a given temperature. The water vapor concentration increases significantly as the temperature rises, approaching 100% (steam, pure water vapor) at 100 °C. However the difference in densities between air and water vapor would still exist (0.598 vs. 1 ...

  4. Nucleate boiling - Wikipedia

    en.wikipedia.org/wiki/Nucleate_boiling

    During transition boiling of water, the bubble formation is so rapid that a vapor film or blanket begins to form at the surface. However, at any point on the surface, the conditions may oscillate between film and nucleate boiling, but the fraction of the total surface covered by the film increases with increasing temperature difference.

  5. Wet-bulb temperature - Wikipedia

    en.wikipedia.org/wiki/Wet-bulb_temperature

    The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.

  6. Vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressure

    The atmospheric pressure boiling point of a liquid (also known as the normal boiling point) is the temperature at which the vapor pressure equals the ambient atmospheric pressure. With any incremental increase in that temperature, the vapor pressure becomes sufficient to overcome atmospheric pressure and cause the liquid to form vapor bubbles.

  7. Surface tension - Wikipedia

    en.wikipedia.org/wiki/Surface_tension

    For a spherical bubble, ... the liquid and vapor phases of pure water Temperature dependency of ... 1994 to conform to the International Temperature Scale of 1990. ...

  8. Mechanism of sonoluminescence - Wikipedia

    en.wikipedia.org/wiki/Mechanism_of_sonoluminescence

    What they all have in common is, a) the interior of the bubble heats up and becomes at least as hot as that measured for MBSL, b) water vapor is the main temperature-limiting factor and c) the averaged temperature over the bubble does not rise higher than 10,000 K. [1]

  9. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    This definition also precisely related the Celsius scale to the Kelvin scale, which defines the SI base unit of thermodynamic temperature with symbol K. Absolute zero, the lowest temperature possible, is defined as being exactly 0 K and −273.15 °C. Until 19 May 2019, the temperature of the triple point of water was defined as exactly 273.16 ...
