Entropy: Embrace the Chaos! Crash Course Chemistry
Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be...

Enthalpy: Crash Course Chemistry
Energy is like the bestest best friend ever and yet, most of the time we take it for granted. Hank feels bad for our friend and wants us to learn more about it so that we can understand what it's trying to tell us - like that any bond...

TED-ED: What triggers a chemical reaction? - Kareem Jarrah
Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by...

The Laws of Thermodynamics, Entropy, and Gibbs Free Energy
We've all heard of the Laws of Thermodynamics, but what are they really? What the heck is entropy and what does it mean for the fate of the universe? How does soap work?! So many questions answered in this clip! Enjoy!

Practice Problem: Calculating Free Energy Change
We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

Spontaneous Processes
In this video Paul Andersen discriminates between spontaneous (or thermodynamically favored) processes and those that are not spontaneous. A spontaneous process requires no external energy source. If the enthalpy change in a reaction is...

Gibbs Free Energy
Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to...

Using Gibbs Free Energy
In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the _G is less than zero the process is spontaneous. If the _G is greater than zero the...

Enthalpy
Sal introduces students to the term, "enthalpy" in this chemistry video. He defines enthalpy as: the internal energy, plus the pressure times the volume found in a system. He constructs a PV diagram to illustrate this point.

Hess's Law and Reaction Enthalpy Change
Sal introduces students to Hess's Law. The law states that the energy change of a process is independent of how we get from one state to another. He sets up a series of reactions, and solves them to illustrate the principles behind...
