Unit I: Matter

  1. 1. M A T T E R A N D I T S P R O P E R T I E S Unit 1
  2. 2. Building Blocks of Matter Mass – A measure of the amount of matter Matter – Anything that has mass and takes up space Atom - Smallest Unit of an element that maintains the chemical identity of that element Element – Pure substance that can be broken down into simpler, stable substances Compound – A substance that can be broken down into simple substances (elements).
  3. 3. Properties and Changes in Matter Intensive Properties – Do not Depend on amount of matter present Extensive Properties – Depend on the amount of matter that is present
  4. 4. States of Matter Solid – State of matter that has a definitive state and volume Liquid – Definite Volume but indefinite shape Gas – Neither definite volume nor shape Plasma – High temperature physical state of matter in which atoms lose most of their electrons, particles that make up atoms
  5. 5. Classification of Matter -Mixtures Mixture – A blend of two or more kinds of matter, each of which retains its own identity and properties Homogeneous Mixture – Uniform in Composition Solution – A homogeneous mixture in which one substance is dissolved in another Heterogeneous Mixture – Non-Uniform in composition Colloid – Particles are mixed together but not dissolved. It will not separate upon standing. The particles are constantly colliding, which allows light to scatter, appearing cloudy. Suspension – Particles mixed together that settle out when standing.
  6. 6. Pure Substances A pure substance has a fixed composition and differs from a mixture in that 1. Every sample of a pure substance have the same characteristics throughout. 2. Every sample of a pure substance has the same composition throughout
  7. 7. Physical Properties and Changes in Matter Physical Property – a characteristic that can be observed or measured without changing the identity of the substance Physical Change – A change in substance that does not involve a change in the identity of a substance Change of State – Changing of a phase of matter
  8. 8. Chemical Properties and Chemical Change Chemical Property – Relates to a substance’s ability to undergo changes that transform it into different substances Chemical Reaction – A change in which one or more substances are converted into different substances Reactants – The substances that react in a chemical change Products – The substances that are formed by the chemical change
  9. 9. Physical VS Chemical Changes Physical substance changes state but does not change its chemical composition. crumpling a sheet of paper melting an ice cube casting silver in a mold breaking a bottle Chemical substance changes into something new. burning wood dissolving salt in water mixing acid and base digesting food
  10. 10. Physical Changes Shape and size changes Mixing and dissolving
  11. 11. Chemical Changes
  12. 12. Reactants and Products Reactants are the substances combined to form Products.
