JEE PYQ: Thermodynamics Question 6
Question 6 - 2021 (18 Mar Shift 2)
An ideal gas in a cylinder is separated by a piston in such a way that the entropy of one part is $S_1$ and that of the other part is $S_2$. Given that $S_1 > S_2$. If the piston is removed then the total entropy of the system will be :
(1) $S_1 \times S_2$
(2) $S_1 - S_2$
(3) $\frac{S_1}{S_2}$
(4) $S_1 + S_2$
Show Answer
Answer: (4)
Solution
Entropy is an extensive property. After piston is removed: $S_{\text{total}} = S_1 + S_2$
