Liquid helium - Wikipedia

Liquid helium is a physical state of helium, at very low temperatures if it is at standard atmospheric pressures. Liquid helium may show superfluidity.. At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −269 °C (about 4 K or −452.2 °F). Its boiling point and critical point depend on which isotope of helium is present: the ...

Introduction to Liquid Helium - NASA

Sep 11, 2014  As a practical matter, a pumped bath of liquid helium 4 can be used to cool down to about 1 Kelvin. A pumped bath of liquid helium 3 can be used to cool down to about 0.3 Kelvin. Superfluid Helium. For helium 4, crogenicists distinguish two liquid forms: helium I and helium II. Helium I is the warmer form; helium II is the colder.
