Product Description

Ball and Ring Apparatus

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.

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 :-

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

Demonstrates thermal expansion

Visual proof that metal expands when heated
