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

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.
