What Is the Water Displacement Method?

The water displacement method is the process of measuring the volume of an irregularly shaped object by immersing it in water. This method served as the basis for the principle developed by the Greek philosopher Archimedes.

Matter is characterized by the rest mass it possesses and the physical space it occupies, also known as the volume. Any material can also be identified by its density, which refers to its mass divided by its volume. However, the volume of irregularly shaped objects cannot be easily determined. The water displacement method conveniently solves this problem. The amount by which the water level rises when an object is submerged is equivalent to the volume of the object. Once the volume is obtained, the density can now be computed.
