One liter of liquid helium expands to 750 liters of helium gas under normal or also called standard conditions (1 bar, room temperature), when going through the boiling point of 4.2 K. The lambda point, the point where liquid helium gets superfluid, is at 2.2 K. Helium is therefore a non-renewable natural resource, the price of which is constantly going up.
