The connections of liquid dynamics to thermodynamics are proven to facilitate understanding the glass transition in liquids. Here, we investigated the melting entropies ΔSmof various materials with the emphasis on its relation to kinetic fragility. The vibrational entropy ΔSvib-exin ΔSmis determined and, a correlation between the ratio of ΔSvib-ex/ΔSmand fragility is shown. The correlation basically reproduces the results determined at glass transition temperatures,Tg, showing the sluggish variation of ΔSvib-ex/ΔSmfromTgup to the melting pointTm. ΔSvib-ex/ΔSmis also found to be related to the ionicity for ionic crystals and toTmfor metals.
