Question

Two containers A and B made up of different materials are heated to the same temperature. It has been observed that container B expands more than container A for same rise in temperature. Comment.

Answer 1

Answer:

Explanation:

2.A wall has two layers A and B, each made of different material. Both the layers have the same thickness. The thermal conductivity of the material of A is twice that of B. Under thermal equilibrium, the temperature difference across the wall is 36° C The temperature difference across the layer A is [1980] a) 6°C b) 12°C
