Why We Can't Invent a Perfect Engine: Crash Course Engineering #10
We’ve introduced the 0th and 1st laws of thermodynamics, so now it’s time to move on to the second law and how we came to understand it. We’ll explain the differences between the first and second law, and we’ll talk about the Carnot...
Crash Course
Heat Engines, Refrigerators, & Cycles: Crash Course Engineering #11
Cycles are a big deal in engineering. Today we’ll explain what they are and how they’re used in heat engines, refrigerators, and heat pumps. We’ll also discuss phase diagrams and the power of using renewable energy resources
NASA
On a Mission: A Matter of Life and Death
Earth is a living, dynamic world thanks to volcanoes and the planetary heat that fuels them. The InSight mission wants to see if Mars also has a heartbeat deep inside its cold exterior.

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...

Khan Academy: Proof: Volume Ratios in a Carnot Cycle
An explanation to prove the volume ratios in a Carnot cycle. [17:08]
Khan Academy
Khan Academy: Chemistry: Carnot Cycle and Carnot Engine
A video lecture discussing the four processes of the Carnot cycle. Each step of the process is described and illustrated relating the temperature change and whether heat was absorbed or released. Also explained is the P-V diagram for the...
Khan Academy
Khan Academy: Chemistry: Carnot Efficiency 3
A video lecture proving the Carnot engine is the most efficient engine. The video starts by explaining the basics of heat engines and the Carnot engine. Then the video compares the efficiency of the Carnot engine and a proposed super...
Khan Academy
Khan Academy: Chemistry: Efficiency of a Carnot Engine
A video lecture defining efficiency for a heat engine and the efficiency of a Carnot engine. Using the area under the PV diagram, the lecture explains how the efficiency of an engine could be calculated. [14:04]
