A simple relation has been obtained for the thermal conductivity ‘λ’ in terms of topological-short-range order parmeter ‘x’. The dependence of ‘λ’ on temperature has thus been studied through the dependence of ‘x’ on ‘T’. The liquid state can be visualized as a system consisting of a large number of atoms which at any instant of time are members of one or the other short-range ordered micro-regions, the size and the mean life of these micro-regions are dependent on temperature. The atomic motions in the liquid state can be described in terms of two distinct motions one, the vibrational motion of the reference atom about its pseudoequilibrium position i.e. its vibrational motion within the ordered micro-region and the second characterizing the change of these pseudoequilibrium positions by diffusion which can also be referred to as the translational motion of the atoms.
