WebAug 29, 2024 · The Second Law because the Sun provides energy to the Earth, thus making it unable to be an isolated system. Explanation: The Second Law of thermodynamics states that the entropy on Earth can only increase unless there is an external source of energy. This external source is the Sun, which makes Earth an open … Web2 Answers. One way in which to show the two statements are equivalent is to show that if one of them is violated then so is the other. We show here that if the Kelvin statement is violated, then so is the Clausius statement. Imagine there were such a things as a perfect heat engine: For each joule of heat extracted from a hot reservoir, exactly ...
