Which of the following compounds will form significant amount of meta product during mono-nitration reaction?
A solid body of constant heat capacity 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 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 :
