Two metal rods—one lead, the other copper—are connected in
Chapter 16, Problem 56P(choose chapter or problem)
Two metal rods—one lead, the other copper—are connected in series, as shown in Figure 16–18. These are the same two rods that were connected in parallel in Example 16–7. Note that each rod is 0.525 m in length and has a square cross section 1.50 cm on a side. The temperature at the lead end of the rods is \(2.00^{\circ} \mathrm{C}\); the temperature at the copper end is \(106^{\circ} \mathrm{C}\).
(a) The average temperature of the two ends is \(54.0^{\circ} \mathrm{C}\). Is the temperature in the middle, at the lead-copper interface, greater than, less than, or equal to \(54.0^{\circ} \mathrm{C}\)? Explain.
(b) Given that the heat flow through each of these rods in 1.00 s is 1.41 J, find the temperature at the lead-copper interface.
