What is entropy? - Jeff Phillips 4,545,329 Views 9,906 Questions Answered TEDEd AnimationLet’s Begin… There’s a concept that’s crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why...
Entropy is an important concept in physics and chemistry, and it also applies to other disciplines, including cosmology and economics. In physics, it is part of thermodynamics, and in chemistry, it is a core concept in physical chemistry. Key Takeaways: Entropy Entropy is a measure of the ra...

Uh, OK. What is entropy? Why does it change? [How to Temporarily Undo the Universe's Endless Chaos with Chloroform] Count the molecules If I gave you a box of air and asked you to measure its properties, your first instinct would be to bust out a ruler and thermometer, recording impor...
The work done, primarily by Boltzmann & Gibbs, on the foundations of statistical mechanics, is of profound significance that can hardly be overestimated. In the hands of Clausius and his contemporarys, entropy was an important, but strictly thermodynamic property. Outside of physics, it simply ha...
Mathematician: In physics, entropy relates to the number of states that a system can be in. If a system actually contained absolutely nothing, then (quantum mechanical considerations aside), it would only have one state, and therefore would have 0 entropy (there would be no uncertainty at all...
Standard calculations suggest that the entropy of our universe is dominated by black holes, whose entropy is of order their area in Planck units, although they comprise only a tiny fraction of its total energy. Statistical entropy is the logarithm of the number of microstates consistent with the...
Entropy in physics is associated with the randomness of a system. It is also used in other fields of study and is used to define the multiplicity of a system or, in the case of information entropy, the average rate of information produced by a source. Entropy was first introduced in ...
This is the definition of entropy as the term is used in physics, as well as its equation and an explanation of misconceptions about the concept.
What is a Diamond Anvil Cell? Discussion Comments Byanon114831— On Sep 30, 2010 No the opposite. Higher entropy means less chaos (energy in the system has dissipated, we are close to the death of the universe, close to equilibrium). Low entropy i.e. when we add more energy to the ...
