Introduction to Liquid Helium

2014-9-11 · For helium 4, crogenicists distinguish two liquid forms: helium I and helium II. Helium I is the warmer form; helium II is the colder. The transition temperature, called the "lambda point", is 2.17 K. (It varies slightly with pressure.) Helium I, the "warm" form, acts more or less like a conventional liquid. Helium II has some strange properties.
