Critical points of the elements

The critical point describes the extreme value of a phase boundary line (binodal), at which a substance undergoes a minimum or maximum of pressure and temperature. At this point, existing phases are fluids (individual particles can move freely in space). Lide (ed), CRC Handbook of Chemistry and Physics, 85th Edition, online version. The pressure value has an uncertainty of ±14%. " International Journal of Thermophysics, volume 15, number 6, 1994, pp. 1007/BF01458840 Enss. . How to ensure accurate weighing results every day?
