Question

A man straightens up his room. His action does not violate the second law of thermodynamics because

• A. the entropy of his room increased
• B. energy of the universe was conserved
• C. the entropy increases by the breakdown of nutrients in his body is greater than the entropy decreases by the straightening of his room
• D. his action violates the second law of thermodynamics

Hint:

According to the second law of thermodynamics, the total entropy of the universe always increases, even if entropy decreases locally.

Answer 1

The Correct Option is C

The second law of thermodynamics allows for local decreases in entropy, as long as the total entropy of the system (including the surroundings) increases. The breakdown of nutrients in his body contributes to this increase.
