The melting point of aluminum is 660°C, its latent heat of fusion Lf 4.00 x 105 J/kg, and its specific heat C = 900J/kg K. How much heat must be added to 500 g of aluminum originally at 27°C to completely melt it? Hint: Use the figure below to organize your thinking. T. Q1 = mcAT Q2 = mLf Tr Qi Q2 The first increment of heat Q1 raises the temperature of the solid Aluminum from its initial temperature T¡ to the fusion temperature Tf in a specific heat process. The second increment of heat Q2 melts the Aluminum in a latent heat process. 14 kJ O 147 kJ 395 kJ 485 kJ O 273 kJ
