    since liquid helium has low viscosity

    do you know the temperature of liquid helium?very low its only 4 k.viscosity of gases increase with increase in temp. but viscosity of liquids decreases with increase in temp.can u guess how these low temp. are produced.

    The adhesive force is greater than the cohition force so the molecules near the walls of the container moves upwards

    the frictionless flow and other exotic behaviour observed in liquid helium at temperatures near absolute zero (−273.15 °C, or −459.67 °F), and (less widely used) similar frictionless behaviour of electrons in a superconducting solid. In each case the unusual behaviour arises from quantum mechanical effects.
