1. Two bars, A and B, each of length 2.0 m and cross sectional area 1.0 m2, are placed end to end as shown in the figure. The thermal conductivities of the bars are kA = 339 J/(s ? m ? K) and kB = 837 J/(s ? m K), respectively. The left end of bar A is maintained at 373 K while the right end of B is maintained at 273 K.

a. What is the rate of heat transfer through this combination?

b. How much heat passes the interface between A and B in 5.0 s?
