Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand the second law of thermodynamics.
According to the second law of thermodynamics, the entropy of an isolated system can never decrease.
The entropy of an isolated system tends to increase or remain constant, but it cannot decrease.
Step 2: Identify the correct option.
Entropy in an isolated system can only increase or stay constant, but it cannot decrease.
According to the second law of thermodynamics, the entropy of an isolated system can never decrease.

- Given below is the plot of the molar conductivity vs \( \sqrt{c} \) concentration for KCl in aqueous solution. If, for the higher concentration of KCl solution, the resistance of the conductivity cell is 100 \( \Omega \), then the resistance of the same cell with the dilute solution is 'x' \( \Omega \). The value of \( x \) is:
