Question

Which of the following statements is a logical consequence of the second law of thermodynamics?
A) If the entropy of a system increases, there must be a corresponding decrease in the entropy of the universe.
B) If there is an increase in the energy of a system, there must be a corresponding decrease in the energy of the rest of the universe.
C) Every chemical reaction must increase the total entropy of the universe.
D) Energy can be transferred or transformed, but it cannot be created or destroyed.

Answer 1

Which of the following statements is a logical consequence of the second law of thermodynamics?

The correct answer is option C - Every chemical reaction must increase the total entropy of the universe.

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time. The processes involving transfer or conversion of heat energy are irreversible and increase the entropy.
