Ball and Ring Apparatus

Gelsonlab HSPT-011 Educational Ball and Ring Apparatus Thermal Expansion Set                                

The molecules and atoms vibrate at higher temperatures and begin to push apart from each other. This phenomenon is known as thermal expansion. Simply heat the brass ball for two minutes. This will cause the ball to expand; hence it will not fit through the ring. When the ball cools down, it will once again fit smoothly through the ring. Great for the classroom or the home laboratory!

Features:

Demonstrates thermal expansion
Visual proof that metal expands when heated
Experiment is easily performed in just two minutes
Great for chemistry teachers in the classroom
Product features
Easily demonstrate how the expansion of metals works
Insulated plastic handles to protect hand from heat
A great economic demonstration for teaching students about the expansions of metals
Includes instructions
 

Product description

The Ball and Ring Apparatus allows for a visible demonstration of the principles of the expansion of metals. When the ball is heated it will not pass through the ring, but when cooled the ball passes through the ring freely. The Ball and Ring are mounted on insulated plastic handles to protect your hands from the heat. Instructions included.
