Introduction to Reaction Profiles: Exothermic and Endothermic Reactions and Activation Energy
This video provides an overview of reaction profiles, explaining the concepts of exothermic and endothermic reactions, as well as activation energy. The presenter defines each of these terms, provides examples of each type of reaction,...

Practice Problem: Calculating Free Energy Change
We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

How Entropy Powers The Earth (Big Picture Ep. 4/5)
This video is about how we don't just need energy to power our lives, we need *low entropy* energy! Thanks to Google Making and Science for supporting this series, and to Sean Carroll for collaborating on it! This video is about how we...

Reversing Entropy with Maxwell's Demon
The second law of thermodynamics - the law that entropy must, on average, increase - has been interpreted as the inevitability of the decay of structure. This is .... misleading. Structure can develop in one region even as the entropy of...

Entropy: Embrace the Chaos! Crash Course Chemistry
Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be...

Entropy
In this video Paul Andersen explains that entropy is simply the dispersion of matter or energy. He begins with a series of video that show the natural direction of processes. According to the second law of thermodynamics the entropy may...

TED-ED: What is entropy? - Jeff Phillips
There's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It's entropy, and it's...

How Quantum Entanglement Creates Entropy
Entropy is surely one of the most perplexing concepts in physics. It’s variously described as a measure of a system’s disorder - or as the amount of useful work that you can get from it - or as the information hidden by the system....

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...

Life Requires Free Energy
Paul Andersen describes how free energy is used by organisms to grow, maintain order, and reproduce. A brief discussion of the first and second law of thermodynamics is also included. Disruptions in the amount of free energy can cause...

Thermodynamics and Energy Diagrams - Crash Course Organic Chemistry
In organic chemistry, different reactions can take place at vastly different speeds. To better understand whether a reaction actually will happen, and how useful that reaction is, we need to understand thermodynamics and kinetics. In...

Using Gibbs Free Energy
In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the _G is less than zero the process is spontaneous. If the _G is greater than zero the...

Entropy : Why is it Predicted to Cause the Heat Death of the Universe?
Heat death of the universe, also called The Big Chill or Big Freeze, will happen when the entropy of the universe will be so high that everything and everyone that lives in it will perish. This will happen because an organism living in...

Measuring Entropy Changes through Calorimetry Experiment
The video discusses how to measure entropy change in chemical reactions through an experiment using calorimetry. It explains the concepts of exothermic and endothermic reactions and how to calculate heat energy change. The equipment used...

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!

How Cells Hack Entropy to Live
One of the most fundamental ideas in physics is that the disorder of the universe, also known as entropy, is constantly increasing. But, life’s inherent chemical makeup has been hacking the disorder of the universe for billions of years!
