3.1: Chapter 3: Introduction to Matter

Difficulty Level: At Grade Created by: CK-12

Chapter Overview

Matter is anything that has mass and volume. Matter has both physical and chemical properties. Elements are pure substances with unique properties. Compounds are unique substances that form when two or more elements combine chemically. Physical changes in matter are changes in physical properties. Chemical changes in matter are changes in chemical properties. Matter cannot be created or destroyed, even when it changes.
