Liquid Helium Cooled

Introduction to Liquid Helium NASA

11/09/2014· Helium 3 boils at Kelvin. This boiling point is one degree colder than that of helium 4. Both helium 4 and helium 3 can be cooled to below their boiling temperatures by reducing the pressure to below atmoshperic pressure. Liquid helium, like water, boils at a lower temperature when the pressure is lower....
