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 temper

Options

  1. A2,2 2
  2. B2 2,8 2
  3. C2,4 2
  4. D2, 2

Correct answer

D. 2, 2

Step-by-step solution

The entropy change of the body in the two cases is same as entropy is a state function.
