hey, can anyone help me with this question? im really having trouble with it.(adsbygoogle = window.adsbygoogle || []).push({});

1. Two metal rods, one lead the other copper, are connected in series (end-to-end). Note that each rod is 0.525m in length and has a square cross section 1.5cm on a side. The temperature at the lead end of the rods is 2 degrees C; the temperature at the copper end is 106 degrees C.

a) The temperature of the two ends is 54 degrees C. Is the temperature in the middle, at the lead-copper interface greater than, less than or equal to 54 degrees C?

b) Given that the heat flow through each of these rods in 1 sec. is 1.41J, find the temperature at the lead-copper interface.
