There's a Loophole in One of the Most Important Laws of Physics
The laws of thermodynamics are cornerstones of physics - but one of them is more breakable than it appears.

Thermodynamics: Crash Course History of Science
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 other that didn't and then some ideas that...

TED-Ed: At what moment are you dead? - Randall Hayes
For as far back as we can trace our existence, humans have been fascinated with death and resurrection. But is resurrection really possible? And what is the actual difference between a living creature and a dead body anyway? Randall...

Where Did Life Come From? (feat. PBS Space Time and Eons!)
The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let's journey back to the...

Life Requires Free Energy
Free energy, get your free energy here! Learners see that all organisms require free energy, which comes from the sun. The lesson explains the first two laws of thermodynamics and then analyzes metabolism, via glycolysis, on a very...

Entropy: Embrace the Chaos!
Chemistry makes it seem that everything has its place and behaves according to different laws. Not always true! Disorder and chaos can and do happen in chemistry; scientists call this disorder entropy. Learn about entropy and its...

What is Entropy?
Entropy, often misunderstood yet easily proven through mathematics, caused confusion for many years. A video explains entropy through simple models. It demonstrates the mathematical proof behind the phenomenon.

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...

How Entropy Powers the Earth (Big Picture Ep. 4/5)
Energy can be either useful or useless, depending on you look at it! A video lesson examines how entropy works with the Law of Conservation of Energy. Scholars learn how Earth receives and uses photons from the sun in a state of low...

Entropy & Free Energy
An understanding of chemical reactions really boils down to two concepts: entropy and enthalpy. Follow along with this instructional video as it explains how these two principles are used to calculate Gibbs free-energy which...

What Is the Purpose of Life? (Big Picture Ep. 5/5)
In the eyes of a physicist, the purpose of life is to continue the mission of the sun. An engaging lesson discusses the increasing entropy levels of energy that originates at the sun. As life forms use that energy, entropy rises until it...

What Triggers a Chemical Reaction?
Chemical reactions are happening all around us every second of every day, but what exactly causes these changes to occur? Using easy-to-understand analogies, this video explains how the concepts of enthalpy and entropy determine the ways...

Why We Can't Invent a Perfect Engine: Crash Course Engineering #10
Your car's engine is likely to be only 20 percent thermally efficient. Why so inefficient? Viewers of the 10th video in an engineering series learn how the second law of thermodynamics and entropy limit the efficiency of a car engine....

Thermodynamics: Crash Course History of Science #26
Scientists discovered the first law of thermodynamics 25 years after the second law of thermodynamics. The seemingly obvious discoveries sometimes confuse scientists while more complex challenges encourage extra study—and take more time...

Carnot Cycle and Carnot Engine
The Carnot Cycle is the focus of this chemistry video. Carnot was a French engineer who proved that energy transfers happen in a cycle. They start and finish at the same pressure, volume, and temperature. A system that completes the...

Work Done by Isothermic Process
Since the temperature of a system is so crucial in its energy transformation, Sal goes into two processes which greatly affect temperature in a system: The Isothermic Process and The Adiabatic Process. He sets up an example, and...

Efficiency of a Carnot Engine
In the world of chemistry, efficiency is defined as: the work a system does, divided by the energy given to that system to complete the work. Sal illustrates this important chemistry concept by drawing a PV graph that shows a Carnot...

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...
