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. `ln2,2ln2`
B. `2ln2,8ln2`
C. `ln2,4ln2`
D. `ln2,ln2`

Answer

D

Explanation

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