What metal best conducts cold?
None. Metals do not stay cold.Metals are very good conductors of heat and so when we touch them they FEEL colder (or hotter) than when we touch other materials that are not as good conductors of heat at the same temperature as the metal. If both are colder (or hotter) than our body temperature, the metal will always feel colder (or hotter) than the other material, because it is able to conduct heat out of (or into) the part of our body in contact with the metal faster than the other material is able to.
