Frequently Asked Questions
Q1. How does the Ball and Ring Apparatus demonstrate thermal expansion?
At room temperature the brass ball passes freely through the ring; once the ball is heated it expands and can no longer pass through, clearly demonstrating thermal expansion until the ball cools back down and fits through again.
