An aluminum ring has an inner radius of 4.9973 cm at room temperature (20 °C). A copper ball has a radius of 5.0035 cm at the same temperature. To what final temperature (in °C) must you heat the ring for the ball (starting from room temperature) to be able to pass through it? (The linear thermal expansion coefficient for aluminum is 2.34 * 10-5 °C-1 and for copper is 1.76 * 10-5 °C-1.)
