Statement - I : Below 2.2 Kelvin, helium is called super fluid
Statement - II : Helium has abnormally low viscosity below 2.2 Kelvin

Statement I is true because at temperatures below 2.2 Kelvin, helium undergoes a phase transition and becomes a superfluid. In this state, helium has zero viscosity and can flow through narrow spaces and capillaries without any resistance.

Statement II is also true because helium has abnormally low viscosity below 2.2 Kelvin. This is because at this temperature, the helium atoms in the superfluid state are in a highly ordered state and move in unison, forming a single quantum mechanical entity called a Bose-Einstein condensate. The absence of any interaction between the particles in the condensate leads to zero viscosity and perfect flow. As a result, helium in the superfluid state is an excellent coolant and is used in a variety of applications, such as in MRI machines and space telescopes.
