Floating Density Ball
Model Number: MTM-47
The Floating Density Ball from Micro Technologies is a hollow metallic sphere designed to demonstrate the effect of temperature on the density of a liquid. When used under suitable experimental conditions, the ball floats in cool water and sinks in warm water, providing a clear visual demonstration of temperature-dependent density and buoyancy. The ball has an approximate diameter of 4 inches and is supplied with instructions.
Product Specification
The Floating Density Ball from Micro Technologies is a physics laboratory apparatus developed for demonstrating how changes in temperature can affect the density of a liquid and the buoyant behavior of an object.
The apparatus consists of a hollow metallic sphere designed to provide a simple and highly visible classroom or laboratory demonstration.
When placed in cool water under appropriate experimental conditions, the ball floats. When transferred to warmer water, it can sink as the density of the surrounding liquid changes.
This behavior provides students with a practical way to investigate the relationship between temperature, liquid density, buoyancy and floating or sinking.
The demonstration is based on the fact that the density of water generally changes with temperature. As the surrounding liquid's density changes, the buoyant force acting on the sphere also changes.
The relationship between buoyant force and displaced liquid can be connected with Archimedes' principle, according to which an immersed object experiences an upward force related to the weight of the fluid it displaces.
When the conditions are suitable for the ball to float, the upward buoyant force can support its weight. When the liquid density is reduced sufficiently, the available buoyant force may no longer support the sphere in the same way, causing it to sink.
This makes the Floating Density Ball useful for connecting multiple physics concepts within a single demonstration, including density, thermal effects, buoyancy, displacement and Archimedes' principle.
The sphere has an approximate diameter of 4 inches, making it large enough to provide a clear visual demonstration during laboratory and instructor-led practical sessions.
Its hollow metallic construction provides the required overall density characteristics while maintaining a convenient spherical form.
Students can compare the behavior of the sphere in water maintained at different temperatures and record their observations.
The apparatus can also support discussions about why temperature must sometimes be considered when performing accurate measurements involving liquids and density.
It provides an effective transition from basic density calculations to more applied discussions about thermal expansion and temperature-dependent physical properties.
The demonstration can complement other density apparatus such as density blocks, specific gravity specimens, displacement vessels and Archimedes principle kits.
Instructions are included to support proper experimental use.
Manufactured and supplied by Micro Technologies, the Floating Density Ball is suitable for physics laboratories and scientific teaching facilities requiring a visual demonstration of the relationship between temperature and liquid density.
