A ring made of brass is to slip in a steel cylinder. At 22.0°C, the brass ring has an inner diameter of 6.000 cm while the diameter of the steel cylinder is 6.050 cm. (a) At what temperature must the ring be brought for it to slip in the cylinder if only the ring will be warmed? (b) If both the ring and the cylinder will be warmed, what must be the corresponding final temperature for the ring to slip in the cylinder?
