Problem

A solid body of constant heat capacity 1 J∘C−11 \text{ J}^\circ\text{C}^{-1} 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∘C100^\circ\text{C} to final temperature 200∘C200^\circ\text{C}. Entropy change of the body in the two cases respectively is : (1) ln⁡2,2ln⁡2\ln 2, 2\ln 2 (2) 2ln⁡2,8ln⁡22\ln 2, 8\ln 2 (3) ln⁡2,4ln⁡2\ln 2, 4\ln 2 (4) ln⁡2,ln⁡2\ln 2, \ln 2
