How much heat in joules must be added to 0.348 kg of aluminum to change it from a solid at 138 °C to a liquid at 660 °C (its melting point)? The latent heat of fusion for aluminum is 4.0 x 105 J/kg.

Look up the specific heat of aluminum. Call it C.
Q = M C *(522) + M*(4.0*10^5)
Where M= 0.348 kg
Compute the heat required, Qj
