THE recently published measurements1 on some properties of condensed helium, in conjunction with the facts known from the work of Keesom and his co-workers2, allow us to draw some conclusions on the behaviour of helium at very low temperatures. 
The thermal conductivity of condensed helium
At low temperatures the thermal conductivity of a condensed phase is very sensitive to structure, and the various phases of condensed helium exhibit a wide range of behavior. The two stable isotopes,

The viscosity of liquid helium has been measured with a flow method between 2 and 5° K . The coefficient of viscosity decreases with decreasing temperature over the whole range. A particularly

The negative coefficient of thermal expansion of He ii is shown to be a consequence of the disordering process which takes place as the temperature rises. The conclusion is reached that the thermal

Measurements have been made of the specific heat at constant volume of solid 3He from 3 K up to the melting point at a number of different densities corresponding to pressures up to 2000 atm. The
The Liquid State at the Absolute Zero and the Third Law of Thermodynamics
TLDR
The thermodynamical requirements for the existence of the liquid state at the absolute zero are examined generally and various possibilities for the thermodynamic behaviour of the helium isotope of mass 3 in the liquidstate are examined.
Helium at elevated pressures: Quantum liquid with non-static shear rigidity
The properties of liquid helium have always been a fascinating subject to scientists. The phonon theory of liquids, taking into account liquid non-static shear rigidity, is employed here for studying
