WebNov 26, 2024 · Boiling point of Helium is -268.9°C. Note that these points are associated with the standard atmospheric pressure. Boiling Point – Saturation In thermodynamics, … WebIn the periodic table of elements, the element with the lowest boiling point is helium. Both the boiling points of rhenium and tungsten exceed 5000 K at standard pressure. Since it is difficult to measure extreme temperatures precisely without bias, both have been cited in the literature as having the higher boiling point. Melting Point WebBoiling point The temperature at which the liquid–gas phase change occurs. ... Despite billions of years of countless stars fusing hydrogen into helium it still makes up 75 per cent of the detectable content of the universe.
