WebThe heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.It is a measure of a substance’s ability to transfer heat through a material by conduction.Note that Fourier’s law applies for all matter, regardless of its state (solid, liquid, or gas), therefore, it is also defined for liquids and … WebCohesive energy; ionic charge; transition metal chalcogenide; pnictides. PACS No. 62.20.-x 1. Introduction Cohesive energy is one of the parameters used to understand the nature of chemical bonding and several important parameters can be predicted using it. Its magni- tude tells us about the stability and chemical reactivity of solids.
