Water displacement can measure the volume of an irregular stone.
Compressing a gas without losing any gas increases its density.
Making an object hollow always increases its average density.
Gas particles are usually closer together than liquid particles.
Read a measuring cylinder with your eye level with the liquid surface.
A gas is compressed without losing any gas. What happens?
