Super Fluidity - What Does It Involve?

Before understanding what super fluidity involves it is important to look at the two most vital components of any experiment conducted on the property. This implies assimilating information on helium 3 and helium 4. Helium 3 is hardly found on the earth but is found in abundance on the moon. Scientists are confident enough that the million tons of helium 3 that is obtained on the moon will be able to provide enough of energy to the people on earth to carry out different activities, for many years to come.

Helium 3 is sure to become a very important cash crop of the moon. Research has proved that helium 3 is of course a fuel that is environment friendly as well as safe for its use on earth; even if it is scarcely available on earth help us studying the effecters of temperature that are at zero degrees. Also the effects of this element on different matter for its superconductivity help researchers in their research. Helium 4 is non toxic and a chemical element with an atomic number 2.

It was in the year 1868 that it was observed by Pierre Janssen a French astronomer. In the solar eclipse in that year he observed spectral line of an unknown yellow color, in the sunlight. The same was observed by Norman Lockyer another astronomer, who proposed this spectral line was formed due to a new element. Lockyer named this element as helium. He and Pierre Janssen have been jointly accredited with the discovery of helium 4. The term super fluidity enjoys a unified description that reveals that super conductivity and the mentioned phenomenon are observed only with the help of yet another phenomenon called breaking of gauge symmetry.

Super fluids or the elements as we know as the highly cooled helium-4, are capable of exhibiting a number of properties that are beyond the usual ones that are observed in the case of other fluids. This can be better understood by conducting a little more research on these unusual properties as seen in the Helium to Helium state experiments. The super fluid is observed to act like a concoction or mixture of the components therein that exhibit normal properties.

The experiments are interesting since the observer gets to learn first hand about the components, their core properties, behavior of normal fluids and the resultant super fluids and its components. The phenomenon results in the super fluid developing a component viscosity of ‘0'. The fluid, the super fluid, also exhibits a zero count in entropy. Along with these zero counts, the fluid also displays thermal conductivity of infinite nature.

This development during the course of the experiment makes it possible to actually get down to setting up a temperature gradient that helps record the temperature count at which the super fluid exhibits different properties from any normal fluid. The setting up of a temperature gradient is not an easy task but not an impossible one either. The experiment once conducted sheds ample of light on the velocity at which the transition takes place.
