1.	Two identical metal rods A and B are joined end to end. The free end of A is kept at 27°C and the free end of B at 37°C. Calculate the temperature of the interface. Thermal conductivity of A = 385 "Wm"^(-1) "K"^(-1), that of B 110 "Wm"^(-1) "K"^(-1).
Answer» SOLUTION :`385 A (T - 300) // L = 110 A (310 A - T) // l, T = 302.2 "K"`
