k2 and k3
Three rods of identical cross-section and lengths are made of three different materials of thermal conductivity K1, K2 and K3, respectively. They are joined together at their ends to make a long rod (see figure). One end of the long rod is maintained at 100°C and the other at 0°C (see figure). If the joints of the rod are at 70°C and 20°C in steady state and there is no loss of energy from the surface of the rod, the correct relationship between K1, K2 and K3 is

The figure shows three different arrangements of materials 1, 2 and 3 ( identical in shape ) to form a wall. The thermal conductivities are k1, k2 and k3 , respectively , and k1 > k2 > k3. The left side of the wall is 20 degree higher than the right side.
