Solve the following problem given below:
Problem: A 6.70kg piece of solid copper metal at an initial temperature T is placed with 2.00 kg of ice that is initially at -22.0 µC. 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 1.00kg of ice and 1.00kg of liquid water.
Part I: What was the initial temperature of the piece of copper?
I need help to solve the above question and express your answer to three significant figures and include the appropriate units.
