Investigations 7 5

  1. 1. Response Sheet – Phase Change <ul><li>Wax is not turning into water – it is melting </li></ul><ul><li>When a solid material is heated enough, it changes phase to a liquid </li></ul><ul><li>Added heat increases the kinetic energy which causes the bonds holding the particles to break and form a liquid </li></ul>
  2. 2. Gas to Solid <ul><li>If water boils and turns into gas, where does it go? </li></ul><ul><li>What does water vapor look like? </li></ul><ul><li>When water turns into water vapor, a gas, is it still water or is it something else? </li></ul><ul><li>How can you tell if water vapor is present? </li></ul>
  3. 3. Set-up Small cup Warm water – NOT TOUCHING BOTTOM OF SMALL CUP Crushed ice Large cup
  4. 4. GET SUPPLIES <ul><li>Supply tray </li></ul><ul><li>Hot water </li></ul><ul><li>Ice (no more than ½ cup) </li></ul>
  5. 5. What do you see? <ul><li>What is it made up of? </li></ul><ul><li>Where did it come from? </li></ul><ul><li>What is happening at the particle level? </li></ul>
  6. 6. What do you see? <ul><li>Condensation </li></ul><ul><li>GAS LIQUID </li></ul><ul><li>Evaporation </li></ul><ul><li>LIQUID GAS </li></ul>
  7. 7. WHY? <ul><li>Where did the water that condensed on the ice cup come from? </li></ul><ul><li>Why did it condense there? </li></ul><ul><li>How could we create </li></ul><ul><li>another phase change? </li></ul>
  8. 8. What is happening? <ul><li>After the salt is added, DON’T touch the water-ice system for several minutes. </li></ul>
  9. 9. Water and Ice Observations <ul><li>Water went through 3 phase changes </li></ul><ul><ul><li>Liquid  Gas </li></ul></ul><ul><ul><li>Gas  Liquid </li></ul></ul><ul><ul><li>Liquid  Solid </li></ul></ul>
  10. 10. Vocabulary – Page 55 <ul><li>Energy Transfer : movement of energy from hot to cold </li></ul><ul><li>Calorie: unit of measurement for energy transfer (measures heat) </li></ul><ul><li>Equilibrium: energy transfer is equal, no change is taking place </li></ul><ul><li>Conservation of Energy : energy can’t be created or destroyed </li></ul>
  11. 11. Vocabulary – Page 55 <ul><li>Phase Change : change from one phase of matter to another, requires heat to be added or taken away </li></ul><ul><li>Freezing : change from a liquid to a solid </li></ul><ul><li>Melting : change from a solid to a liquid </li></ul><ul><li>Evaporation : change from a liquid to a gas </li></ul><ul><li>Condensation : change from a gas to a liquid </li></ul>
