1 The Properties of Matter
Chapter 1 Notes The Properties of Matter

2 What is Matter? Matter is anything that has Mass and Volume
Mass is the amount of matter an object contains. Units: grams (g), kilograms (kg) Volume is the amount of space an object takes up. Units: liters (L), milliliters (mL), cubic centimeters (cm3)

3 Vocabulary YOU need to know!

4 Physical vs. Chemical Properties

5 Physical Properties Physical properties can be observed or measured without changing the identity of the matter. Examples: Color Odor Mass Volume Density (Density = Mass/Volume) State – Solid, Liquid, or Gas? Malleability – Can I flatten it? Ductility – Can I stretch it into a thin wire? Solubility – Can I dissolve it in something? Thermal Conductivity – Does it carry heat?


7 Chemical Properties Chemical properties describe a substance’s ability to change into a new, different substance. Examples: Flammability – Does it burn? Reactivity – Does it react when mixed?


9 Characteristic Properties
Characteristic properties are always the same, whether the object is large or small. Characteristic properties can be physical or chemical. Examples: Density Solubility Reactivity

10 Physical Changes In a physical change, a physical property changes, but the identity of the substance does not change. Physical changes are sometimes easy to undo Examples: Melting ice or boiling water Ripping paper into pieces Dissolving sugar into water


12 Chemical Changes In a chemical change, a substance changes into a different substance. Chemical changes are usually difficult to undo. Examples: Burning wood or “snakes” Spoiling milk (curdling) Rusting metal
