A block of copper has a volume of 5.5x10-3 m3 and a mass of 50.0 kg. The specific heat capacity of copper is 385 J/(kgC0). The melting point of copper is 1085 0C. The latent heat of fusion is Lf = 2.05x105 J/kg. The coefficient of volume thermal expansion is c = 17x10-6/C0. A) How much heat is absorbed by the copper block to melt it and create liquid copper at a temperature of 1085 0C starting from 300 C? B) What is the volume of the copper block when the temperature reaches 950 0C starting from 30 0C?
