In this interactive object, learners use the ideal gas law to solve a practice problem.
Melting Point and Freezing Point
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners observe that the melting of a solid and the freezing of its liquid occur at the same temperature. The melting point is an intrinsic property and is used to identify a substance.
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.
Product Yields in Chemical Reactions
Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.
