A 1.67-kg block of aluminum at 21.7°C is to be melted and reshaped. How much heat must flow into the block in order to melt it?

use the following values:

For copper:

c_copper=0.386 kJ/kg.K

T_fusion=1359 K

L_fusion=205 kg/K

For aluminum:

c_aluminum=0.900 kJ/kg.K

T_fusion=932 K

L_fusion=396 kg/K
