a year ago. First it’s helpful to properly define entropy, which is a measurement of how dispersed matter and energy are in a certain region at a particular temperature. Since entropy is primarily dealing with energy, it’s intrinsically a thermodynamic property (there isn’t a non-thermodynamic entropy).

- Entropy is not energy; entropy is how the energy in the universe is distributed. There is a constant amount of energy in the universe, but the way...
- It's just a tendency of the universe. We, as living beings, fight against the increase of entropy in our bodies, as a result, it's a little bad for...

- It is because water when it goes from 4 degrees celsius to less, expands in volume and thus gains entropy.
- Yes. More configurations = more entropy. In fact, entropy = K times the log of the number of configurations. S=K log W, or S=K log omega. (To reall...

- A black hole has the maximum possible entropy for the volume of space inside their event horizon.
- lowest entropy: solid hight entropy: plasma Because the particles in a solid are least dispersed, the entropy is lowest. It is the opposite with pl...

Video transcript. - [Instructor] The concept of entropy is related to the idea of microstates. And to think about microstates, let's consider one mole of an ideal gas. So remember, n represents moles at a specific pressure, volume, and temperature. If the system of gas particles is at equilibrium, then the pressure, the volume, the number of ...

Entropy is just the measure of chaos within a system. The more disordered a system is, the more entropy it has. For example, a neat deck of playing cards has little entropy. However, if you throw the deck in the air, all the cards will go in random directions. Now, the cards have more entropy.
