Transcript of "Mid Summative 5 7 Answers"

  1. 1. <ul><li>Ice cream mixture 22ºC </li></ul><ul><li>Ice/salt mixture -15 º C </li></ul><ul><li>Kitchen counter 38 º C </li></ul>22 -15 38 Energy always flows from HOT to COLD
  2. 2. COLD milk + HOT cocoa <ul><li>Energy flows TO the milk </li></ul><ul><li>Energy flows FROM the hot chocolate </li></ul>
  3. 3. Particles, Kinetic Energy, & Energy Transfer <ul><li>Kinetic energy is the energy of moving particles. The more kinetic energy a particle has, the faster it moves. When one particle collides with another, energy is transferred between particles (Hot to cold) </li></ul>
  4. 4. Calculating Calories 250 (50 x 5) Raise the temperature of 50 g of water 5ºC 10 (10 x 1) Raise the temperature of 10 g of water 1ºC Calories
  5. 5. MELT FREEZE EVAPORATE CONDENSE <ul><li>K.E. increased , particles got further apart </li></ul><ul><li>K.E. decreased , particles got closer together </li></ul><ul><li>K.E. increased , particles got farther apart </li></ul><ul><li>K.E. decreased , particles got closer together </li></ul>
  6. 6. Equilibrium <ul><li>Both hot and cold particles collided with each other and transferred energy. This continued to happen until all had reached a common temperature (warm) and the energy transfer between the colliding particles was equal. </li></ul>
  7. 7. Stuck Toys <ul><li>Applying ice would cause the toys to CONTRACT, both the kinetic energy and the volume would decrease and the toy would get smaller </li></ul><ul><li>Applying heat would cause the toys to EXPAND, both the kinetic energy and the volume would increase and the toy would get larger </li></ul>
  8. 8. Vocabulary page 63 <ul><li>Mixture : 2 or more substances mixed together </li></ul><ul><li>Solution : A mixture formed when one substance dissolves in another </li></ul><ul><li>Solute : A substance that dissolves in another </li></ul><ul><li>Solvent : A substance in which a solute dissolves </li></ul>
  9. 9. Read How Things Dissolve Pages 49 – 53 Answer questions (page 62)
