Once the aluminum ring in Problem 20 is slipped over the bar, the ring and bar are

Question:

Once the aluminum ring in Problem 20 is slipped over the bar, the ring and bar are allowed to equilibrate at a temperature of 22 °C. The ring is now stuck on the bar.

(a) If the temperatures of both the ring and the bar are changed together, should the system be heated or cooled to remove the ring?

(b) Find the temperature at which the ring can be removed.
