At 20.0°C, an aluminum ring has an inner diameter of 5.00 cm and a brass rod has a diameter of 5.055 cm. (a)If only the ring is warmed, what temperature must it reach so that it will just slip over the rod? (b) If both the ring and the rod are warmed together, what temperature must they both reach so that the ring barely slips over the rod? (c) Why might the temperature value of part (b)pose problems for this system?ANS = 478.3 °C, 2315.972 °C

I cannot get the anwser for part B, I keep on getting 2901.61 C! Thanks:)
