WebNov 20, 2024 · Helium – Boiling Point. Boiling point of Helium is -268.9°C. Note that, the boiling point associated with the standard atmospheric pressure. In general, boiling is a phase change of a substance from the liquid to the gas phase. The boiling point of a substance is the temperature at which this phase change (boiling or vaporization) occurs. WebAug 8, 2024 · The freezing point of helium is so low because it does not have a large nucleus. Helium has two protons and two neutrons in its nucleus, which means it has a small atomic number. This makes helium atoms very weakly held together, meaning they can easily break apart and freeze. WebMay 17, 2024 · The freezing point of helium is -272.2 ° C (-458.0 ° F). Helium is the only gas that cannot be made into a solid simply by lowering the temperature. It is also necessary to increase the pressure on the gas in order to make it a solid. At a temperature of about -271 ° C (-456 ° F), helium undergoes an unusual change. It remains a liquid, but ... javascript print image from url
