A solid body of constant heat capacity 1 J/°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 :
  • a)
     ln2, 2ln2
  • b)
    2ln2, 8ln2
  • c)
     ln2, 4ln2
  • d)
    ln2, ln2
Correct answer is option 'D'. Can you explain this answer?
