Liquid helium-4, .., liquid .He behaves in many ways as though it was actually a mixture of . separate fluids, one of which is devoid of entropy and viscosity (see §5.2). No such behaviour occurs above T., where the properties of the liquid are quite ordinary by comparison, being rather similar to those expected of a dense classical gas of hard spheres.
