Webb22 okt. 1995 · Liquid Helium is called a "quantum fluid" as it displays atomic properties on a macroscopic scale. The viscosity of liquid helium is 25 micropoises (water has a viscosity of 10,000 micropoises). As helium is cooled below its transition point, it has an unusual property of superfluidity with a viscosity approaching zero micropoises. WebbAnswer (1 of 7): Helium is an inert gas by nature. It is from the group called Noble gases in the periodic table. It can be considered as the most noble gas of all as it exists as a gas even in the extreme cases and it has the lowest boiling and melting points.Following are the Physical Properties of Helium:- Odorless- Tasteless- Colorless- Boiling point of …
