Creetical pynt (thermodynamics)

Frae Wikipedia, the free beuk o knawledge
(Reguidit frae Creetical temperatur)
1. Subcritical ethane, liquid an gas phase coexist
2. Critical pynt (32.17 °C, 48.72 bar), opalescence
3. Supercritical ethane, fluid[1]

In thermodynamics, a creetical pynt (or creetical state) is the end pynt o a phase equilibrium curve. The maist prominent example is the liquid-vapour creetical pynt, the end pynt o the pressur-temperatur curve that designates condeetions unner which a liquid an its vapour can coexeest.
