A video lecture to explain what entropy is and what it isn't. Two definition of entropy are introduced and explored to show how they can be reconciled. Also investigated is the second law of thermodynamics and its relationship to...

It's time to heat things up! LITERALLY! It's time for Hank to talk about the history of Thermodynamics!!! It's messy and there are a lot of people who came up with some ideas that worked and others that didn't and then some ideas that...

Introduction to entropy, and how entropy relates to the number of possible states for a system. [7:26]

Understand the 2nd Law of Thermodynamics. Disorder is a pretty big deal in the universe and that makes it a pretty big deal in chemistry - it's such a big deal that scientists have a special name for it: entropy. In chemistry, entropy is...

Clarifying that the thermodynamic definition of Entropy requires a reversible system. [15:38]

Long video explaining why entropy is a measure of the number of states a system can take on. [28:26]

Distinguishing between microstates and macro states. How entropy S is defined for a system and not for a specific microstate. [8:56]

Proof that S or entropy is a valid state variable. [15:38]

Introduces second law of thermodynamics. A discussion of entropy change in terms of heat and microstates. [19:15]

Did you know why heat increases entropy? This covers how entropy relates to biology and how it can do some work! [7:01]

This video looks at why the 'proof' of the relation between changes in Gibbs Free Energy and Spontaneity is wrong in many textbooks. [6:40]
