Maintaining An Aluminum Boat How Do I Solve This Thermal Process Physics Problem?

How do I solve this thermal process physics problem? - maintaining an aluminum boat

An aluminum rod and bar iron butt in a good thermal contact. The two bars are of equal length and radius. The free end of the aluminum rod is kept at a temperature of 100 ยบ C, and the free end of the rod of iron is kept at 0 ° C (a) Find the temperature of the interface between the two bars. (b) If each rod is 15cm long and each has a cross section of 5.0 cm ^ 2, the amount of energy through the combination in 30 minutes?

To determine the thermal conductivity of various metals, and how long it takes for the temperature it from spreading to the other end of it, provided that they caught both determined at room temperature (300 K)

To resolve this problem, the thermal conductivity of aluminum and iron are required.Unfortunately have not delivered.
Produces the basic equation for the quantity of heat, the T1 by a rod of length l 'and the cross-section' a 'in time' t second is the formula Q = KA (- T2) T / L given where T1 and T2 are The temperature differences between the ends.
