Latent Heats: The melting point of aluminum is 660°C, its latent heat of fusion is 4.00 × 105 J/kg, and its specific heat is 900 J/kg ? K. If 300 kJ of heat are added to 442 g of aluminum at 100°C, what is the final state of the system? That is, how much is liquid, how much is solid, and what is its temperature?
What will be an ideal response?
The system will be at 660°C, with 249 g of solid and 193 g of liquid aluminum.
