    How to derive Relation between Levi-civita Density and Kronecker's Delta?

    The Relation between Levi-Civita Density and Kroneckers Delta as follows \sum^{3}_{k=1} \epsilon_{mnk} \epsilon_{ijk} = \delta_{mi} \delta_{nj} - \delta_{mj} \delta_{ni} Logically we can satisfy both sides of the expression but Can anyone tell me how to derive this analytically ?

    Why does the liquid-vapor interface disappear at critical temperature?

    Mr.Ehild, First of all thanks a lot for your reply. The Reference you have given in your reply helps a lot to understand the term "Critical Temperature". Ultimately I just reached to a conclusion that "at Critical temperature [ in general ] The distinction between liquid and vapor disappears as...

    Why does the liquid-vapor interface disappear at critical temperature?

    As far as I know an interface is a tool and concept that refers to a point/layer of interaction between components/ Different substances. :)

    Why does the liquid-vapor interface disappear at critical temperature?

    [FONT="Book Antiqua"]While Studying 'surface tension' I came across a statement that 'At critical Temperature the interface between liquid and its vapour disappears' without any explanation or logic. Can Anyone please tell me why such phenomenon is observed at critical temperature ? Thanks in...
