Entropy might be the truest scientific concept that the fewest people actually understand. Answer. Closed system can be reversible or irreversible. The concept of entropy can be very confusing — partly because there are actually different types.The Hungarian mathematician John von Neumann lamented the situation thusly: "Whoever uses the term 'entropy' in a discussion always wins since no one knows what entropy really … The second law states that the entropy of a system never decreases. The entropy of the universe is increasing for a given. Entropy (S) by the modern definition is the amount of energy dispersal in a system. The entropy of the universe is increasing For a given change to be spontaneous. Both the burning of fuel (mostly through fusion in stars) and the distribution of heat are processes which increase entropy. The system entropy (S) by the modern definition is the amount of energy dispersal in a system. Therefore, the system entropy will increase when the amount of motion within the system increases. Maybe we can look at entropy in a simpler way. Our universe is marching very, very slowly towards equilibrium! $\begingroup$ I need to think more, but usually you define a system and surrounding, and these may make up your universe. According to second law of thermodynamics , the entropy of the universe always increases in the course of every spontaneous (natural) change . II. KCET 2007: Entropy of the universe is (A) continuously increasing (B) continuously decreasing (C) zero (D) constant. I. $\begingroup$ If life is decreasing local entropy and therefore decreasing entropy per volume, it is relevant to the question. Entropy is Confusing. Pages 15. School Beirut Arab University; Course Title CHEMISTRY 000; Uploaded By saadramadanaw. For example, the entropy increases when ice (solid) melts to give water (liquid). ... For a closed system, the entropy can increase, decrease or remain constant. Entropy per volume is more important than total entropy. If you want more depth have a peek at the laws of thermodynamics. The vast majority of the universe is already screaming cold, so the heat death of the universe is just about burning what fuel there is and mixing the heat so created into the ever-expansive, cold, and unyielding cosmos. Physics, Ph.D. Student, UC Berkeley The second law of thermodynamics says that the total entropy of the universe can never decrease. Basically entropy is a reflection of the statement that "It's easier to destroy than to build". I posit that yes, the entropy of the universe is increasing so long as we take the laws of thermodynamics to be true and our universe is an isolated macroscopic system. This preview shows page 5 - 10 out of 15 pages. The entropy of the universe will always increase. But in terms of the universe, and the very long-term, very large-scale picture, the entropy of the universe is increasing, and so the availability of energy to do work is constantly decreasing. Answered by: Brent Nelson, M.A. Check Answer and Solution for abo Since expansion of the Universe is continually reducing the observable universe, entropy per volume is more relevant.
