Maxwell's Demon | Thermodynamics | Second Law

From the creator

Maxwell's Demon. Maxwell's famous thought experiment. Can we break the second law of thermodynamics? Can entropy be reversed? Hi! I'm Jade. I draw pictures that move and become animated physics videos. ***SUBSCRIBE*** https://www.youtube.com/c/upandatom ***Let's be friends*** TWITTER: https://twitter.com/upndatom?lang=en ***MORE VIDEOS YOU'LL LOVE*** Quantum Paradox: The Exploding Bomb and the Photon - https://youtu.be/wiW7jhdKDVA Why Does Time Go Forward? https://youtu.be/PUr5dR0q3UE MUSIC: bensound.com __________________________________________________________________ Today we are going to try to break the second law of thermodynamics! Remember that law? It comes in many forms: 1. The entropy/disorder of the universe is always increasing. But it can also be written as 2. The energy in the universe available to do useful work is always decreasing. When things are in a low entropy ordered state, they can do what scientists call "useful work". Imagine a box with hot air on one side and cold air on the other. This is a very ordered low entropy state, and the temperature difference can be used to power an engine or create electricity. As the air reaches thermal equilibrium, the energy available to do useful work has decreased, until it becomes nothing at all. This will never spontaneously reverse into useful, hot and cold air again. Unless outside work is put in, like a heat pump. But the work used by the heat pump to create the temperature difference is always goin
