The Science of Energy - Resources and Power Explained
Energy is, without a doubt, the very foundation of the universe. It's the engine that powers life and fuels the evolution of human civilization. Yet for all its importance, what energy really is and how it works remains a mystery to most non-scientists. For example:
  • Where does most of…
Stoichiometry Problems
You extend your study of stoichiometry to consider more complex problems involving volume, molecules, and energy.
The Mole
One of the most important concepts to master in an introductory chemistry course is the concept of the mole, which provides chemists with a way to "count" atoms and molecules. Learn how scientists use the mole and explore the quantitative definition of this basic unit.
Chemistry, 2nd Edition Course
Many students struggle in high school chemistry. Even if they succeed in earning a good grade, they often still feel confused and unconfident. Why is this? And what can be done to help every student succeed in this vitally important course? Success in chemistry, according to veteran science teacher Professor…
Energy Efficiency - Technologies and Trends
Episode 21 of The Science of Energy
Where is energy commonly being wasted? How does one become a more efficient energy user? This lecture is filled with takeaways to help anyone (from home owner to car driver to CEO) become more energy efficient in a range of sectors and settings: industries, transportation, residences, and commercial buildings.
Fuels and Explosives
Episode 16 of The Nature of Matter
Study the different ways that stored chemical energy is released in substances such as gasoline, coal, natural gas, nitroglycerine, and TNT. Learn the difference between detonation, which is what high explosives do, and deflagration, which happens to the fuel in an internal combustion engine.
Energy Needs for Transportation
Episode 20 of The Science of Energy
Transportation is an enormous part of our global total energy consumption. From planes to trains to automobiles, learn how scientists are working to make popular modes of transportation as fuel-efficient as possible. Also, explore the topic of electric cars and whether or not they're truly more efficient than gas-powered ones.
Writing and Balancing Chemical Equations
What happens when you combine two or more elements? Through a variety of practice problems, you learn to identify when a chemical reaction has occurred, how to write chemical equations, and how to "balance" equations to conserve the atoms.
The Structure of Atoms and Molecules
Episode 4 of The Nature of Matter
Understand atomic and molecular structure with the help of a simple analogy: the rooms of a house and the collection of houses in a city. See how the electrons of an atom occupy shells, subshells, and orbitals, which give atoms and molecules their distinctive properties.
Isotopes and Families of Elements
Discover how isotopes, which are different atoms of the same element, can actually differ in their weight because they contain different numbers of neutrons in their nuclei. Also, learn how different kinds of elements are grouped into both general categories (such as metals and nonmetals) as well as specific chemical…
Energy - Forms and Conversion for Use
Episode 2 of The Science of Energy
Energy is a fundamental part of our universe--in a sense, the universe is energy. Here, Professor Wysession introduces you to the many fascinating forms energy takes, including potential, kinetic, mechanical, and thermal energy. He also explains how energy is measured to make you more fluent in "energy-speak" for the coming…
