What Are Physical Changes In Matter 1

  1. 1. What are Physical Changes in Matter? Lesson #2
  2. 2. States of Matter <ul><li>Three States of Matter </li></ul><ul><li>-solid </li></ul><ul><li>-liquid </li></ul><ul><li>-gas </li></ul><ul><li>-Every substance on Earth can exist as a solid, as a liquid, or as a gas. </li></ul><ul><li>-The difference between them is in the way the particles move. </li></ul><ul><li>Example: Water </li></ul>
  3. 3. Solid <ul><li>Particles are close together (do not move) and just vibrate in place. </li></ul>
  4. 4. Liquid <ul><li>Particles that are close to each other, but also they move quickly and slide past each other easily. </li></ul>
  5. 5. Gas <ul><li>Particles are far apart and moving really fast. </li></ul>
  6. 6. 4 Ways Substances Can Change State change of state -occurs when a substance changes from one another. Each change of state has its own name. <ul><li>solid to a liquid </li></ul><ul><li>liquid to a gas </li></ul><ul><li>gas to a liquid </li></ul><ul><li>liquid to a solid </li></ul><ul><li>-melting </li></ul><ul><li>-boiling </li></ul><ul><li>-condensing </li></ul><ul><li>-freezing </li></ul>
  7. 7. Physical Changes <ul><li>physical change- is a change that does not result in a new substance. </li></ul><ul><li>Examples of Physical Changes </li></ul><ul><li>-cut, rip, fold, crumple, shred, carve, etc… </li></ul><ul><li>(also changes in state- melting, freezing, boiling, and condensing) </li></ul><ul><li>In a physical change, no new substance is formed. </li></ul><ul><li>Example- If you shred paper. What is left? (paper) What you started with is what you ended with! </li></ul>
  8. 8. Mixtures <ul><li>In science, mixtures have a specific definition which is two or more substances that combine without changing any of them . </li></ul><ul><li>Example: salad, vegetable soup, soil, lemonade, chocolate milk, etc… </li></ul><ul><li>-Not all mixtures are made of solids, but most materials are found in nature. </li></ul><ul><li>-Remember being in a mixture DOES NOT change the substance and mixtures can be separated back out. </li></ul>
