IMPRINTS OF PARENT CRYSTAL-STRUCTURE IN THE LIQUID-PHASE - THERMAL-CONDUCTIVITY

The existence of short-range order (SRO) in liquids can be visualised as the signature of parent crystal structure on this phase. The absenc e of long-range order (LRO) substantially affects the properties of li quids. The problem of heat conduction through simple liquids has been studied considering the effects of both the persistence of SRO and abs ence of LRO. A relation has been deduced for the thermal conductivity lambda of simple liquids, which also gives the variation of the therma l conductivity with temperature. The calculated values of lambda for i nert elements viz. neon, argon and krypton are found to be in good agr eement with experimental data.
