Web30 Mar 2024 · The second law is universally contemplated among the great laws of Nature, although no two scientists will tell you what it is in the same way, except when they agree to coauthor a paper (e.g. [ 4 – 6, 15 – 24 ]) or a book (e.g. [ 3, 25 – 30 ]). Our understanding of the laws of thermodynamics has never stopped evolving over the past two centuries. Web2. Second Law of Thermodynamics - the disorder of the universe, a system and its surroundings, always increases for a process that occurs naturally; that is, without the input of external matter or energy into the system. 3.
