Question

A copper block and a wooden block having similar dimensions are subjected to the same temperature at one face of each block. The other face of the blocks will reach the same temperture at a rate which is:

• A. Faster in wooden block.
• B. Faster in copper block.
• C. Equal in wooden as well as copper block.
• D. Cannot be predicted with given data.

Answer 1

The correct option is B Faster in copper block.

Thermal conductivity of copper is more than the thermal condutivity of wood. So, heat transfer rate will be faster in copper.
Hence , option (b) is the correct answer.
