Copper is a reddish metal with a face-centered cubic crystalline structure. It reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure, so it as a nice reddish color. It is malleable, ductile, and an extremely good conductor of both heat and electricity. The normal freezing point of copper is 1085°C, and its molar enthalpy of fusion is ΔH fusion = 13.2 kJ/mol. What is the entropy change of the system when (5.00g *Class number) of Cu (s) freezes at the normal freezing point? Molar mass of Cu = 63.55 g/mol
