Question

Consider two cylindrical metal rods with
equal cross section—one lead, the other aluminum—connected in
series. The temperature at the lead end of the rods is 22.5 °C; the
temperature at the aluminum end is 85.0 °C. (a) Given that the temperature at the lead-aluminum interface is 52.5 °C, and that the lead
rod is 14.5 cm long, what condition can you use to find the length of
the aluminum rod? (b) Find the length of the aluminum rod
