Helium (He) Helium Linde Gas

Helium (He) is a colourless, odourless, nontoxic, noncorrosive and noncombustible gas. It is mainly sourced from natural gas wells. This valuable gas is in short supply the world over, which is why many appliions incorporate recovery and recycling systems. With the lowest boiling point of any gas (4.2 Kelvin or –269°

Supersolid Wikipedia

Superfluidity in helium arises from the normal liquid by a secondorder phase transition ("lambda transition"). In a dilute gas of Bose particles it comes about by a phase transition that belongs to the universality class of the spherical model. In thin liquid helium films, it arises from the normal liquid by a KosterlitzThouless
