  2. Liquid oxygen - Wikipedia

    en.wikipedia.org/wiki/Liquid_oxygen

    Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (15 psi).

  4. Solid oxygen - Wikipedia

    en.wikipedia.org/wiki/Solid_oxygen

    Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O 2 , like liquid oxygen , is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.

  6. Triple point - Wikipedia

    en.wikipedia.org/wiki/Triple_point

    For most substances, the gas–liquid–solid triple point is the minimum temperature where the liquid can exist. For water, this is not the case. The melting point of ordinary ice decreases with pressure, as shown by the phase diagram's dashed green line. Just below the triple point, compression at a constant temperature transforms water vapor ...

  7. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    The commonly known phases solid, liquid and vapor are separated by phase boundaries, i.e. pressuretemperature combinations where two phases can coexist. At the triple point, all three phases can coexist. However, the liquid–vapor boundary terminates in an endpoint at some critical temperature T c and critical pressure p c. This is the ...

  8. Melting point - Wikipedia

    en.wikipedia.org/wiki/Melting_point

    At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point or crystallization point.
