Three geometrically identical slabs A,B and C have thermal conductivities k,k and 3k. In any configuration of these, extreme left face is always kept at 100∘C while extreme right face is always kept at 0∘C. Consider two configurations shown.The difference (in ∘C) of temperatures of mid-points of the two configurations is 100n . Find n.

6 identical rods of same material are kept as shown in figure. The ends A and B are maintained at 60∘C and 0∘C respectively. The temperature of point Q will be

A brass rod with a length of 20.0 cm is placed side by side with an aluminum rod with a length of 20.0 cm, and this system is placed between a hot temperature of 150 °C and a cold temperature of −10.0 °C. The thermal conductivities of the brass and the aluminum are 100 W/m °C and 230 W/m °C, respectively. The rods have the same cross-sectional area of 20.0 cm2. What is the rate of heat flow from the hot temperature to the cold temperature?
