A 6.00-kg piece of solid copper metal at an initial tem- perature T is placed with 2.00 kg of ice that is initially at -20.0°C. The ice is in an insulated container of negligible mass and no heat is exchanged with the surroundings. After thermal equilibrium is reached, there is 1.20 kg of ice and 0.80 kg of liquid water. What was the initial temperature of the piece of copper? What is the change in entropy for the copper metal and ice?
The initial temperature of the copper is 150 C. How do I get to this answer. And solve for the change in entropy for the copper metal and ice.
