Reversibility & Irreversibility: Crash Course Engineering #8
How do we design the most efficient machines and processes? Today we’ll try to figure that out as we discuss heat & work, reversibility & irreversibility, and how to use efficiency to measure a system.

Spontaneity
It explains the transfer of heat from colder to warmer bodies, relation between entropy and spontaneity,Gibbs energy and spontaneity.

The Second Law of Thermodynamics: Heat Flow, Entropy, and Microstates
What the heck is entropy?! You've heard a dozen different explanations. Disorder, microstates, Carnot engines... so many different wordings and interpretations! Really, they are all related, so let's go through a few different...

Bozeman Science: Second Law of Thermodynamics
In the following video Paul Andersen explains how the second law of thermodynamics applies to reversible and irreversible processes. In a reversible process the net change in entropy is zero. In and irreversible process the entropy will...

Khan Academy: Chemistry: More Rigorous Gibb's Free Energy
A video lecture that derives the Gibb's free energy equation. The video starts by reviewing what a irreversible and reversible process is with explanations and diagrams. While describing irreversible and spontaneous process the formula...

Khan Academy: Chemistry: Quasi Static and Reversible Processes
Understand that an almost static process is called quasi-static process in this video lecture. Also explained is how all reversible processes are quasi-static but not all quasi-static processes are reversible. Video lecture gives...

Khan Academy: Chemistry: Thermodynamic Entropy Definition Clarification
Understand that thermodynamic entropy does not deal with the heat added and the different temperatures at which it is added but rather the reversible heat and temperature to calculate the change in entropy. This video lecture reminds...
