Expt.8 thermal conductivity of copper
WebMaterials with a high thermal conductivity constant k k k k (like metals and stones) will conduct heat well both ways; into or out of the material. So if your skin comes into contact with metal that is colder than your skin temperature, the metal can rapidly transfer heat energy out of your hand, making the metal feel particularly cold. WebThe thermal conductivity of copper is 400 watts per meter kelvin. It implies that area 'A' and thickness 'L' of a plate of copper will conduct heat at a rate of 400.A/L.ΔT joules per …
