Ball and Ring Apparatus
Ball and Ring Apparatus is a classic piece of physics laboratory equipment used to demonstrate the thermal expansion of solids. It consists of a metal ball and a metal ring mounted on a handle. At room temperature, the ball just passes through the ring. When the ball is heated, it expands and can no longer fit through the ring, thus providing a clear and simple demonstration of how heat causes expansion in solids.
Product Information:-
A brass ball secured to a mounted brass ring with a chain
For use in demonstrating thermal expansion
Apparatus demonstrates that the ball passes through the ring when cold but will not pass through after being heated
Ball measures 22mm in diameter, ring to handle measures 9.75″
Excellent demonstration tool for science classrooms
Features:-
- Made of durable metal for repeated laboratory use.
- Wooden or insulated handle for safe handling.
- Compact design, easy to use in classroom demonstrations.
- Effectively illustrates the principle of thermal expansion and contraction.
- Suitable for physics experiments, school labs, and science demonstrations.
Educational Value:-
- Demonstrates the effect of temperature on the dimensions of solids.
- Helps students visualize and understand the concept of expansion and contraction due to heat.
- Useful in explaining real-life applications such as railway tracks, bridges, and metal fittings where thermal expansion plays a role.
