A copper block and an air mass block having similar dimensions are subjected to symmetrical heat transfer from one face of each block. The other face of the block will be reaching to the same temperature at a rate
  • a)
    faster in air block
  • b)
    faster in copper block
  • c)
    equal in air as well as copper block
  • d)
    cannot be predicted with the given information
Correct answer is option 'B'. Can you explain this answer?

A copper block and an air mass block having similar dimensions are su...
Thermal conductivity of copper is around 380 W/mK and air is around 0.026 W/mK. Since thermal conductivity of copper is higher than air, hence heat flow will be faster in copper blocks.

Explanation:
- Thermal conductivity: Copper has a much higher thermal conductivity compared to air. This means that heat is transferred more efficiently through copper than through air.
- Rate of heat transfer: Due to the higher thermal conductivity of copper, heat will transfer faster through the copper block compared to the air block.
- Temperature equalization: As a result, the face of the copper block will reach the same temperature as the face of the air block at a faster rate. This is because the copper block can conduct the heat more quickly, leading to quicker temperature equalization.
- Conclusion: Therefore, the face of the copper block will reach the same temperature at a faster rate compared to the air block in this scenario.
