An insulated box has a barrier that confines a gas to only one side of the box. The barrier springs a leak, allowing the gas to flow and occupy both sides of the box. Which statement best describes the entropy of this system? A) The entropy is greater in the first state, with all the gas on one side of the box. B) The entropy is greater in the second state, with the gas on both sides of the box. C) The entropy is the same in both states, since no heat was added to the gas and its temperature did not change.
