Properties and Changes of Matter: Purpose: The purpose of this experiment is for students to examine and describe the physical properties of various substances while causing some physical and/or chemical changes. In addition to this, students will learn some useful laboratory techniques and learn to make observations and comparisons when working in a chemical laboratory. Introduction: All material in the universe is referred to as matter, which is all that has mass and occupies space. Matter can exist in three different physical states: gas, liquid, or solid. A fixed composition is a sample of matter that has identical properties throughout. Physical properties are those that can be observed and measured without changing the composition, and include: color, odor, density, solubility, boiling point, melting point, and physical state. Every substance also has chemical properties that describe the behavior of a substance when a substance is undergoing a change in composition in a chemical reaction. Procedures:
