Mass and Volume – Basic Principles
How it works
Mass is a property of substances and indicates how much matter is contained in an object. It is measured in kilograms (kg) or grams (g). Volume describes the space an object occupies, and is measured in liters (l), milliliters (ml) or cubic centimeters (cm³). Mass and volume are fundamental physical quantities that are determined with measuring instruments such as a scale (for mass) and a graduated cylinder (for volume). Different substances can have different masses for the same volume (density). Mass remains the same when location changes; volume can change, for example, with changes in temperature.
Mass measures the amount of matter of an object (e. g. in kg), volume the space occupied (e. g. in l or cm³). These are different physical quantities, determined with different measuring instruments; so they do not measure the same thing.
