KCET 2007: Entropy of the universe is (A) continuously increasing (B) continuously decreasing (C) zero (D) constant. Answered by: Brent Nelson, M.A. The entropy of the universe will always increase. School Beirut Arab University; Course Title CHEMISTRY 000; Uploaded By saadramadanaw. The second law states that the entropy of a system never decreases. For example, the entropy increases when ice (solid) melts to give water (liquid). Entropy per volume is more important than total entropy. Since expansion of the Universe is continually reducing the observable universe, entropy per volume is more relevant. Entropy (S) by the modern definition is the amount of energy dispersal in a system. Physics, Ph.D. Student, UC Berkeley The second law of thermodynamics says that the total entropy of the universe can never decrease. Pages 15. 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. II. Our universe is marching very, very slowly towards equilibrium! This preview shows page 5 - 10 out of 15 pages. The system may increase or decrease, but the surrounding will more than compensate this to ensure the entropy of the universe … ... For a closed system, the entropy can increase, decrease or remain constant. $\begingroup$ I need to think more, but usually you define a system and surrounding, and these may make up your universe. The system entropy (S) by the modern definition is the amount of energy dispersal in a system. Entropy might be the truest scientific concept that the fewest people actually understand. 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. Basically entropy is a reflection of the statement that "It's easier to destroy than to build". I. Maybe we can look at entropy in a simpler way. The entropy of the universe is increasing for a given. Entropy is Confusing. According to second law of thermodynamics , the entropy of the universe always increases in the course of every spontaneous (natural) change . $\begingroup$ If life is decreasing local entropy and therefore decreasing entropy per volume, it is relevant to the question. 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 … 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. Therefore, the system entropy will increase when the amount of motion within the system increases. Answer. Both the burning of fuel (mostly through fusion in stars) and the distribution of heat are processes which increase entropy. The entropy of the universe is increasing For a given change to be spontaneous.
