A solid body of constant heat capacity 1 J / ^ ^ C is being heated...
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 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 to final temperature . Entropy change of the body in the two cases respectively is:
Options
- A
- B
- C
- D
Correct answer
D.
Step-by-step solution
The entropy change of the body in the two cases is same as entropy is a state function.
