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...

You are made of polymers, and so are trees and telephones and toys. A polymer is a long chain of identical molecules (or monomers) with a range of useful properties, like toughness or stretchiness -- and it turns out, we just can't live...

People like to say all kinds of things about protein – like, you need to eat lots of it to build muscle and lose weight. The truth is, the science of protein and how your body uses it is much more complicated than that.

One of the problems with the whole idea of a single Scientific Revolution is that some disciplines decided not to join any revolution. And others just took a long time to get there.

Oxidation-reduction reactions are going on around us, and inside us, all the time, and we can make redox reactions in organic chemistry easier to understand by tracking carbon-oxygen bonds. In this episode of Crash Course Organic...

Paul Andersen explains three major nuclear processes; fusion, fission, and decay. He begins with a brief discussion of the four fundamental forces in nature. He the explains how nuclei can be combined in fusion, divided through...

In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains...

There's a lake so deadly that anything that goes for a swim gets pickled. Yet there's a thriving ecosystem literally living on the edge, which might give astrobiologists a hint at how life could thrive on other worlds.

Mr. Andersen explains the basics of balancing chemical equations. A visual guide shows you how to change coefficients to balance the atoms in reactants and products.

Why does changing just one proton in the nucleus of an atom make a different element? How can a single proton make such a huge difference in an element’s properties?



The simple answer is: The number of...

We take a deep dive to understand how chemistry works at a fundamental level. All chemistry is about electrons. They are the primary drivers responsible for an atom’s behavior in chemical reactions, or more precisely the way...

SUMMARY

In this video, I show Why Some Reactions EXPLODE and Others COOL: Root Cause of Chemical EnergyI I show how the chemistry behind endothermic and exothermic reactions can be traced to the underlying quantum...

In this video, we're going to show you how to balance chemical equations – it's going to be easy! We'll start with the basics, and then move on to more complex problems. By the end of this video, you'll be able to balance chemical...

When trying to determine or prove if a chemical reaction has occurred, there are 5 indicators that scientist look for! The 5 indicators are the formation of a precipitate, the formation of a gas, the formation of water, a color change or...

Combustion chemical reactions are reactions that burn a fuel. The fuel that is burned is a hydrocarbon and we all know that oxygen is needed for something to burn. So all combustion reactions will have the reactants of a hydrocarbon and...

In acid and base chemistry, we learn that there are 3 main types of hydrolysis: salt, acid and base. In this video, I will show you a fun and crafty way to spice up your organic chemistry notes on this topic.

Join Vincent, Agathe, David, and Jules as they experiment with different methods to extinguish 100 candles. From using boomerangs and chemical reactions to sound waves and an air cannon, this video explores the science behind each...

In this video, I'm going to show you a simple way to identify the type of chemical reaction that is happening in a given situation. This will help you to understand the process more easily and to carry out the reaction in a more accurate...

Plants, unlike most living things, produce their own food through a process called photosynthesis. Photosynthesis means 'making using light'. Plants use the energy from the sunlight to make food. The food matter comes from carbon dioxide...
