Question:
A solid body of constant heat capacity 1 J/°C is being heated by keeping it in contact with reservoirs in two ways:
A solid body of constant heat capacity 1 J/°C is being heated by keeping it in contact with reservoirs in two ways:
Show Hint
In heat transfer, increasing the number of reservoirs can increase the total heat supplied to the system, leading to a higher temperature rise.

- Sequentially keeping in contact with 2 reservoirs such that each reservoir supplies same amount of heat.
- Sequentially keeping in contact with 8 reservoirs such that each reservoir supplies same amount of heat.
- Sequentially keeping in contact with 2 reservoirs such that each reservoir supplies different amount of heat.
- Sequentially keeping in contact with 8 reservoirs such that each reservoir supplies different amount of heat.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Heat transfer calculation.
The temperature change depends on the number of reservoirs and the amount of heat transferred. More reservoirs supplying the same amount of heat results in a more efficient temperature increase.
Thus, the correct answer is (4).
