Question
A wall is made up of two layers A and B. The thickness of the two layers is the same, but materials are different. The thermal conductivity of A is double than that of B. In thermal equilibrium the temperature difference between the two ends is 36oC. Then the difference of temperature at the two surfaces of A will be
Options
A.6oC
B.12oC
C.18oC
D.24oC
