A physical property of a pure substance is anything that can we can observe without changing its identity. For example, A copper wire transfers heat from one end to the other, but it still consists of copper at every point. WitrynaThermal conductivity is the property of a material to conduct heat. Heat transfer occurs at a lower rate across materials of low thermal conductivity than across materials of high thermal conductivity. This property is temperature dependent and its reciprocal is thermal resistivity. streampunks rpg group
