Brass ring and ball assembly: Enables clear visual demonstration of thermal expansion and contraction
Simple operation: Easily heats and cools to observe the phenomenon
Durable brass construction: Ensures long-lasting use in educational settings
Educational tool: Ideal for teaching fundamental thermodynamics concepts
Summarized by Shop
A ‘s Gravesande’s ring is an apparatus for demonstrating thermal expansion and contraction, a fundamental principle in thermodynamics.
Named after Dutch scientist Willem ‘s Gravesande, the apparatus consists of two main components: a brass ring, and a brass ball slightly smaller in diameter than the ring. The ball can pass freely through

Received the science demo of thermodynamics, advice to improve make the ring tighter tolerance change to an aluminum ring so the heat of your hand can show the temperature difference at the ring
