• Their physical properties are used to observe and describe matter.

The main physical characteristics of matter are mass, volume, weight, density, odor, and color. Why do you need to study physical properties of matter?

• All things are made of matter.

• Matter is anything that occupy space and has mass.

• Matter typically exists in one of three states: solid, liquid, or gas.

• Properties of matter help you to see matter, feel matter, and taste matter.
