The Statue of Liberty stands 93 meters tall in New York Harbor. It is made of the metal copper. Copper is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity and as a building material, as we see here. When copper is exposed to air or seawater over a period of time it reacts to form this blue-green color called verdigris. Copper has a density of 8.96 g·cm3. It will melt at 1084.62oC.
