Question

The value of entropy in the universe is:

• A. constant
• B. decreasing
• C. increasing
• D. zero

Answer 1

The correct option is C increasing

The second law of thermodynamics states that the process is spontaneous if and only if the entropy of the universe increases.

$({\Delta S}_{universe}>0or{\Delta S}_{sys}+{\Delta S}_{surr}>0)$

Entropy (S) is the measure of randomness or disorder of the molecules.
