Gelsonlab Set Thermal expansion, demonstration

The molecules and atoms vibrate at higher temperatures and begin to drift away from each other. This phenomenon is known as thermal expansion. With this device you will easily demonstrate it. Just warm the brass ball in two minutes. This will lead to an expansion of the ball, which is why it will not fit in the ring. Once again, it will slip smoothly through the ring. Great solution for the classroom or home lab!

It's demonstrating thermal expansion.

Visual proof that the metal expands when heated.

The experiment is easy to do in just two minutes.

Insulated plastic handles to protect hands from heat.

Great economic demonstration for teaching students about the expansion of metals.

It includes instructions.
