WebMay 22, 2024 · Thermal Conductivity. The 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 ... WebLower case lambda, $\lambda$, is the molar ionic conductivity. Upper case lambda, $\Lambda$, is the molar conductivity. $\lambda = t \dfrac{\Lambda}{\nu}$ Where $\nu$ is the number of ions for the cation or anion in the molecule. So $\ce{Na3PO4}$ would have 3 cations per molecule, but only 1 anion per molecule.
