In these videos and articles the definition of electric charge will be given as well as a discussion of the law of conservation of charge. You’ll learn how Coulomb’s law relates the electric force to charge and separation distance. The difference between an electrically conducting vs. electrically insulating material will also be discussed.

In these videos and articles you’ll learn about the Celsius and Kelvin temperature scales. The definition of a mole of a substance will be given. You’ll also learn how the ideal gas law relates the pressure, volume, and temperature of a gas. Lastly, you’ll learn how the Maxwell-Boltzmann distribution gives the probability of finding a gas molecule moving at a specific speed.
