  1. Chemistry! The study of the composition, structure, properties, and reactions of a substance.

  2. Matter Pure Substances Mixtures Elements Compounds Heterogeneous Homogeneous Matter

  3. States of matter • Solid: The structure and the volume are defined. Particules don’t have energy to move. Strong attraction between atomes.

  4. States of matter • Liquid: The volume is defined but the structure is not. Particules can move slightly but the force of attraction is still great

  5. States of matter • Gas: The volume and the structure are not defined Particules have enough energy to counterbalance the force of attraction so they can move independantly.

  6. Physical properties • Physical properties can be observed without changing the type of matter. • Examples of physical properties include: • Texture -- Shape • Size -- Color • Odor -- Volume • Mass -- Weight • density

  7. Chemical properties • Chemical properties describe how a substance changes into a new substance. • Ex: • ability to burn • ability to react with another substance

  8. Physical changes • When objects undergo a change that does not change their chemical nature. • A physical change involves a change in physical properties. • Ex: Making a baseball bat. Wood is crafted into a shape. The physical properties have changed but the chemical nature of the wood has not been altered.

  9. Chemical changes • When substances become new or different substances. • Ex: Fireworks are actually metals such as magnesium and copper that change chemically as they light up the night skies with their fantastic colors. • To identify a chemical change look for observable signs such as color change, bubbling and fizzing, light production, smoke, and presence of heat.
