A solid body of constant heat capacity is being heated by keeping it in contact with reservoirs in two ways :
(i) Sequentially keeping in contact with reservoirs such that each reservoir supplies same amount of heat.
(ii) Sequentially keeping in contact with reservoirs such that each reservoir supplies same amount of heat.
In both the cases body is brought from initial temperature to final temperature . Entropy change of the body in the two cases respectively is :
