Two plates A and B have thermal conductivities 84 W m -1 K -1 and 126 W m -1 K -1 respectively. They have same surface area and same thickness. They are placed in contact along their surfaces. If the temperatures of the outer surfaces of A and B are kept at 100° C and 0°C respectively, then the temperature of the surface of contact in steady state is_____°C.
Text Solution
Verified by ExpertsThe correct answer is:
40
(40)
Let the temperature of the contact surface be T,
So, H A = H B
