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 :

Options

A. ln2, 2ln 2
B. 2ln2, 8 ln2
C. ln2, 4ln 2
D. ln2, ln2

Answer

D

Explanation

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