A measure of the ability of a material to allow the flow of heat from its warmer surface through the material to itscolder surface, determined as the heat energy transferred per unit of time and per unit of surface area divided by thetemperature gradient, which is the temperature difference divided by the distance between the two surfaces (thethickness of the material), expressed in watts per kelvin per meter

Heat is a form of energy which transfers between bodies which are kept under thermal interactions.…
