A Novel Way to Measure Density

Description

• leçon - matière potentielle : scale
• cours - matière potentielle : on density

A Novel Way to Measure the Density of a Solid By David Chandler, Porterville College I was recently explaining to a middle school teacher how to measure the density of a solid object (that is denser than water) by comparing its weight in air and its weight suspended in water. The measured weight when suspended in water is the actual weight minus the buoyant force. Archimedes Principle equates the buoyant force to the weight of the water displaced.

• buoyancy reaction
• revised method
• mass of the ball by the volume of the ball
• method to students
• precision for the volume measurement
• buoyant force
• pan
• ball
• beaker
