A solid body of constant heat capacity 1...

A solid body of constant heat capacity `1J//^@C` is being heated by keeping it 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 reservoir 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 tow cases respectively is :

A

In2, 4ln2

B

In2, In2

C

In2, 2ln2

D

2ln2, 8ln2

Text Solution

Verified by Experts

The correct Answer is:
B
Since, entropy is a state function, hence change in entropy in both the processes should be same.
