Required information A 0.560-kg piece of solid lead at 20.0°C is placed into an insulated container holding 0.980 kg of liquid lead at 420°C. The system comes to an equilibrium temperature with no loss of heat to the environment. Ignore the heat capacity of the container. The melting point of lead is 327°C and its heat of fusion is 22.9 kJ/kg and the specific heat of lead is 0.130 kJ/kg K. At equilibrium what will happen to the solid lead? v (Click to select) Some solid lead remains. The solid lead will not melt. All the solid lead becomes liquid.
