A wall has two layers

A

and

B

, made of two different materials. The thermal conductivity of material

A

is twice that of

B

. If the two layers have same thickness and under thermal equilibrium, the temperature difference across the wall is

{48^0}C

, the temperature difference across layer

B

View answer and explanation

Correct option: B

{32^0}C

Option B (

{32^0}C

) is correct because the temperature difference across a layer is inversely proportional to its thermal conductivity when the heat flow is constant.
