When helium-4 is cooled to below 2.17 Kelvin (-271 °C ), it becomes a Superfluid , with properties that are very unlike those of an ordinary liquid. For example, if helium-4 is kept in an open vessel, a thin film will climb up the sides of the vessel and overflow. This strange behaviour is a result of the Clausius-Clapeyron Relation and cannot be explained by the current Model of Classical Mechanics nor by Nuclear or Electrical models.
