Unit 1: Matter & Measurement Properties of Matter

What is matter? • Anything that has mass and volume and is made of atoms. Examples: air, clouds, smoke, ice, liquid water, water vapor, DNA, proteins, etc. • Energy is NOT matter. Examples of energy: light, heat, X-rays, UV radiation, etc.

Kinetic Theory of Matter is made up of particles which are in continual random motion.

STATES OF MATTER SOLIDS • Particles of solids are tightly packed, vibrating about a fixed position. Heat

STATES OF MATTER LIQUID § Particles of liquids are tightly packed, but are far enough apart to slide over one another. Heat

STATES OF MATTER GAS § Particles of gases are very far apart and move freely.

Physical properties of Matter A physical property is a quality or condition of a substance that can be observed or measured without changing the substance’s composition. Examples: - Texture - Color - State (solid, liquid, gas) - Conductivity - Ductility (ability to be stretched into a wire) - Malleability (ability to be bent into shapes) - Melting Point - Boiling Point - Density

Chemical Properties of Matter The ability of a substance to combine with or change into one or more other substances is called a chemical property. – Iron forming rust – Copper turning green in the air
