Principles of Energy and Energy Transfers
This is a video presentation that discusses the principles of energy. It starts by defining different types of energy stores such as kinetic, gravitational potential, elastic potential, thermal, chemical, electrical, and internal energy....

The Third Law of Thermodynamics: Absolute Zero
Brr, it's so cold today! Could it get any colder? Is there a coldest possible temperature? Yes, there is! That seems strange, but now we know that temperature is just a measure of kinetic energy, so zero kinetic energy must mean zero...

The Relationship between Gas Pressure and Volume at Constant Temperature
The video discusses the relationship between the pressure and volume of a gas at constant temperature. The video also introduces the equation PV = constant, which relates pressure and volume for a fixed mass of gas held at constant...

Elastic and Inelastic Collisions
When you take a shot on a pool table or tackle someone in a football game, you're participating in a collision. But the two events we just mentioned are totally different kinds of collisions! We have to learn the varieties and what they...

Energy Transfers and Transformations in Different Systems
This video discusses energy transfers within different systems. It provides five examples, including the energy transfer when a ball is projected vertically upwards, when a moving object hits an obstacle, when brakes are applied to slow...

Temperature
This program covers the very important topic of temperature. We discuss temperature scales and why temperature is important when discussing chemical reactions. We also discuss how to convert from one temperature scale to the other. The...

The First Law of Thermodynamics: Internal Energy, Heat, and Work
In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in...

State of the system
It explains the state of the system by state functions or state variables and describes internal energy as a state function.
Professor Dave Explains
Internal Energy
We know about kinetic energy and potential energy, which can interchange when an object moves through a gravitational field, so let's add to that list the internal energy of the object. This gives us a new and comprehensive way to...
