In this video Paul Andersen explains how the activation energy is a measure of the amount of energy required for a chemical reaction to occur. Due to the collision theory the activation energy requires proper energy and orientation of...

How did we come up with our system of telling time? Why do we divide the day into 24 hours of 60 minutes each, and put 60 seconds in each minute? Where does the definition of a second come from? And who decides what clock shows the...

We're continuing our look at engineering materials with third main type of material that you'll encounter as an engineer: polymers. They're made of long, repeating chains of smaller molecules known as monomers and today we'll explore...

Our early ancestors relied on lightning to cause forest fires, from which they could collect coals and burning sticks to help them cook food and clear land. Yet, it wasn't just humans who benefited from these natural phenomena. Even as...

Why does fire burn? What's the chemistry and physics of a flame? This week, learn about the beautiful science happening inside a flame!

Different fuels create different types of fires, and each one needs to be extinguished using a specific strategy. Do you know which class of extinguisher is needed for different fires?

In this video Paul Andersen explains how the First Law of Thermodynamics applies to an ideal gas in a piston. A pressure-volume graph can be used to determine the type of thermodynamic process. Included is a discussion of and P-V...
