In this text, we delve into the physical property of density by understanding mass, volume, and their relationship to density. Learn about measuring methods, units, and how to calculate density for various substances. Discover why objects sink or float based on their density compared to water.

A closer look at the physical property of Density Let’s review 1. What is mass? Mass is the amount of matter in substance. It is measured using a triple beam balance. The unit of measure is the gram/kilogram.
2. What is volume? Volume is the amount of space that a substance takes ups. It is measured using different methods. 1. Liquid Volume is measured using a graduated cylinder. The unit is mL. 2. Regular Solid Volume is measured using cubic units, L X W X H. The unit is cm³.
3. Irregular solids volume are measured using water displacement. Using graduated cylinder and the amount of water is displaced by an object. - Units mL converted to cm³ Density is a comparison of the amount of matter in a given space. Compare grams to mL or cm³. Mass ÷ Volume = Density Water has a density of 1.0 g/cm³(mL) If an object has a density greater than 1.0 g/mL it will sink in water. If an object has a density less than 1.0 g/mL it will float in water.
