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...

Free Energy of Dissolution
We've learned a lot about solution chemistry, and we've also learned about thermodynamics and spontaneity. So what about the spontaneity associated with dissolution? If an ionic solid dissolves in water, is this an enthalpically or...

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!

Gibbs Free Energy
Energy is neither created nor destroyed, but what about free energy? Where does that fit into thermodynamics? In the video, learners explore simple the spontaneous reaction examples of enthalpy, entropy, and temperature, and then apply...
