Properties of liquid helium | SpringerLink

The reason why helium remains liquid at such low temperatures is that the zero point or ground state motion of the helium atoms is able to outbalance the weak van der Waals forces attracting the atoms together. The two isotopes behave similarly near their boiling points at atmospheric pressure (Table 3.1); they are like dense classical gases.
