WebOak Wood – Thermal Conductivity. Thermal conductivity of Oak Wood is 0.17 W/ (m·K). 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. WebAnswer (1 of 15): It is because the “Wood” is not an element. It is a compound. All the “elements” arranged in an order depending on their atomic number, mass number, atomic weight etc. This arrangement is called as the “Periodic Table”. Element, molecule and compound are different from each ot...
