The heat capacity of a substance is the amount of heat needed to raise the temperature of a certain amount (usually 1 gram) of that substance by 1 degree C.
WebTools In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature. [1] Thermal conductivity is often measured with laser flash analysis. Alternative measurements are also established.
