volume

The best way to find the volume is that it depends on what volume u want to measure and what phase the material is if u want to measure the specific volume of a liquid,a volumetric flask or volumetric pippete is the best if u want to measure avariable amount of liquid a gratuated cylinder is the best.If u want to measure a small amount of liquid a micro pippete is the best.

If you want to measure the volume of a solid,the best way is to submerege the solid in a liquid
in which the solid is completely insoluble and measure the volume change before and after a graduated cylinder
