How do you measure the volume of a rock using a displacement can?

Answer 1

Apparatus needed: Displacement can, sinker such as rock, calibrated beaker, string to attach to rock, tripod stand ( not necessary ) or level surface.

Fill displacement can with water, place on tripod stand or flat surface, at the opening or ' side shoot ' of displacement can place calibrated beaker.

Dip or place the rock with string attached into water of displacement can, a volume of water will flow or fall through the opening of displacement can, into calibrated beaker.

This water, known as the excess water is equivalent to that of the volume of rock, simply observe the meniscus ( of calibrated beaker) and that measure will be the volume.
