In this interactive object, students examine a type of chemical bond known as the "hydrogen bond."
Heat of Fusion and Heat of Vaporization
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine graphs and read that the heat of fusion is the heat energy absorbed by one mole of solid as it is converted to liquid, while the heat of vaporization is the heat energy absorbed by one mole of liquid as it is converted to gas.
The Kinetic Theory of Gases
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.
Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.
By Jill Larson
In this interactive object, the learner examines how pressure and volume relate to each other.
