Learners examine how the boiling point increases with increasing pressure. An example from industry is given.
The Effect of Temperature on the Vapor Pressure of a Liquid
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.
In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
Gas Volume vs. Temperature (Charles's Law)
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.
Balancing Oxidation-Reduction Equations
In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.
