Chapter 10, Problem 10.2P
Interpretation Introduction

Interpretation:

The change in entropy should be determined for the mixture of nitrogen and argon gases kept in separate vessels, when the partition is removed. The gases should be assumed to be ideal and they mix adiabatically and completely.

Concept introduction:

The given systems mix adiabatically which means that there will be no change in heat of the system. Hence, if q1 is heat of vessel 1 and q2is heat of vessel 2 then,

q1+q2=0

It means that,

Heat lost by the argon system= Heat gained by the nitrogen system.

Now, total change in entropy is identified by the addition of all changes in entropy for all paths.
