How does molecular structure affect entropy
WebThe law and the formula essentially state that the universe naturally prefers greater levels of entropy and allows any process which causes a positive increase, but prohibits any process which causes a negative increase. WebOct 17, 2024 · Eventually, the entropy did change, but the formula you used wasn't the right one, and hence it suggested that entropy wouldn't change. The Wikipedia page on entropy has a list of useful formulas , you'll need to choose the appropriate one for different situations, depending on what factors you're maintaining as constants.
