A solid body of constant heat capacity 1J/°C is being heated by keeping it in contact with reservoirs in two ways: |
(i) Sequentially keeping in contact with 2 reservoirs such that each reservoir supplies same amount of heat. |
(ii) Sequentially keeping in contact with 8 reservoirs such that each reservoir supplies same amount of heat. |
In both the cases body is brought from initial temperature 100°C to final temperature 200°C. Entropy change of the body in the two cases respectively is: [JEE MAIN 2015] |
