Question 2

The melting point of aluminum is 660C, its latent heat of fusion is 4.00  105 J/kg, and its specific heat is 900 J/kg  K.
 
  If 300 kJ of thermal energy are added to 442 g of aluminum at 100C, what is the final state of the system? That is, how much is liquid, how much is solid, and what is its temperature?
