A wall has two layers A and B each made of the different materials. The thickness of both the layers is the same. The thermal conductivity of A, KA = 3 KB (thermal conductivity of B). The temperature across the wall is 20°C in thermal equilibrium1.the temperature difference across A = 1C2.rate of heat transfer across A is more than across B3.rate of heat transfer across both is not same4.temperature difference across A is 5°C plz. ans. this with reason..........
