Problem 10.14 (Zemansky)
Two
identical bodies of constant heat capacity are at the same initial
temperature
|
Solution: Click For PDF Version We are given that we have two identical bodies each of mass m at temperature![]() ![]() ![]() ![]()
And the amount of heat delivered by the refrigerator to the body 1 will be
Temperature
of body 1 will have got raised from
From this equation, we find
We next calculate the change in entropy of the body 1 and that of the body 2.
And
The total change of entropy in the process will be
From the entropy principle
Minimum amount of work will be done on the refrigerator in the process for which That is
