Entropy - Episode 39

Entropy. It's why everything seems to break down and get messy. It is something that comes about when you have lots and lots of little things (like atoms) that can be in several possible "states" (no, not Florida). The more things or more states you have, the more entropy you're going to have. Dr. Carlson has entirely too much fun playing with coins and blocks while he tries to explain how Chemists think of Entropy. (Stay to the end and you'll even see a rubber band, whee!)

Entropy is of no greater importance than in the second law of thermodynamics, according to which the total entropy of any system cannot decrease other than increasing the entropy of some other system. Hence, in a system isolated from its surroundings, the entropy cannot decrease. It follows that heat cannot flow from a colder to a hotter body without the application of work to the system. Secondly, it is impossible for any device operating on a cycle to produce net work from a single temperature reservoir; the production of net work requires flow of heat from a hotter to a cooler reservoir. As a result, there is no possibility of a "perpetual motion" system. Finally, it follows that a reduction in the increase of entropy in a specified process, such as a chemical reaction, means that it is energetically more efficient. I am a college sophomore with a dual major in Physics and Mathematics @ University of California, Santa Barbara. By the way, i came across these excellent physics flash cards. Its also a great initiative by the FunnelBrain team. Amazing!!
