WebHelium (i.e., 4He) was first liquefied by H. K. Onnes in 1908. Its normal boiling point is 4 K, and it is now known that helium will never solidify, even at 0 K, at ambient pressure. Liquid helium undergoes a phase change at 2.2 K, the so-called lambda transition, where it has maximum density and heat capacity. Above the lambda transition, it is called liquid … Web4 apr. 2010 · What is the normal phase for helium? Heliums normal phase is a gas.
