In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.
The Effect of Temperature on the Vapor Pressure of a Liquid
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 object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.
In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.
In this animated activity, students view the plastic pellets in a profile extrusion machine being melted as the temperature of the heating elements is elevated by a time proportioning control system.
Students examine the four factors that affect resistance of a wire: temperature, length, diameter, and the type of material from which it is made. A short quiz completes the activity.
