Which of the following statements is true of an isolated system consisting of 15 gas molecules?

Question

Quizplus · Accepted Answer

The second law of thermodynamics states that the entropy of an isolated system will tend to increase over time. Therefore, the entropy of the gas in the isolated system consisting of 15 gas molecules is not likely to decrease (option C). However, it is not necessarily true that the entropy must stay the same (option E) or cannot increase (option D) because the system could gain energy or encounter other changes that increase its entropy. Option A is also incorrect because the second law does not state that entropy cannot decrease, only that it tends to increase. Option B is simply incorrect.
