what does the second law of thermodynamics say about entropy?

a. the total entropy of the universe is increasing.

b. the total entropy of the universe is constant.

c. the total entropy of the universe is zero.

d. the total entropy of the universe is decreasing.

Explanation:

The second law of thermodynamics states that in any spontaneous process, the total entropy of an isolated system (the universe, in a broad sense) always increases over time. Option A aligns with this principle. Option B is incorrect as entropy is not constant in real - world (non - reversible) processes. Option C is wrong because the universe is not a system with zero entropy. Option D is also incorrect as entropy does not decrease in the universe according to the second law.

Answer:

A. The total entropy of the universe is increasing.
