NettetThis is because the pan is made up of metal that can conduct the heat energy due to molecular movement from one point to another. Almost all non-living substances are divided into conductors and insulators of heat energy. For example, aluminium, steel, iron, and others are considered good heat conductors. On the other hand, wood, glass, … NettetThermal conductivity k is measured in watts-per-meter per kelvin (W·m −1 ·K −1 or W/m/K). This is because heat transfer, measured as power, has been found to be (approximately) proportional to . difference of temperature ; the surface area of thermal contact; the inverse of the thickness of the material ; From this, it follows that the power …
