Helium-4 makes up about one quarter of the ordinary matter in the universe by mass, with almost all of the rest being hydrogen. When liquid helium-4 is cooled to below 2.17 kelvins (−271.17 °C), it becomes a superfluid, with properties that are very unlike those of an ordinary

It is named after the Greek word helios. It displays red-orange color when exposed in an electric field. Helium is a monoatomic lightest noble gas found in nature. Stay tuned with BYJU’S for more information!! 2019-05-04 · We know everything we need to find the volume now except the number of moles of gas.
