Question: Two metal rods-one lead, the other copper- are connected in series, as shown in FIGURE 16-29. These are the same two rods that were connected

Two metal rods-one lead, the other copper- are connected in series, as shown in FIGURE 16-29. These are the same two rods that were connected in parallel in Example 16-16. 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 2.00Â°C; the temperature at the copper end is 106Â°C.

(a) The average temperature of the two ends is 54.0Â°C. Is the temperature in the middle, at the lead-copper interface, greater than, less than, or equal to 54.0Â°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.
