The temperature drop through each layer of a two layer furnace wall is shown in figure. Assume that the external temperature T1 and T3 are maintained constant and T1>T3. If the thickness of the layers X1 and X2 are the same, which of the following statements are correct.
K1=K2 but heat flow through material (1) is larger then through (2)
K1=K2 but heat flow through material (1) is less then through (2)
