Mid Summative Exam 4 Answers

  1. 1. When a volume of air is HEATED the kinetic energy INCREASES which causes the particles to move FASTER and this results in the space between the particles INCREASING which causes the volume to increase and this is called EXPANSION
  2. 2. <ul><li>The kinetic energy of the water particles increased when Amy put the hot wrap on the cold bottle </li></ul><ul><li>The water level in the tube went down (up the tube) because the kinetic energy increased which caused the volume of water to increase </li></ul>
  3. 3. <ul><li>The bolt </li></ul><ul><li>Ice would cause the bolt to contract </li></ul><ul><li>Kinetic energy would decrease as the temperature goes down. This would cause the space between the particles to decrease and the object would contract </li></ul>
  4. 4. Can you compress a liquid? <ul><li>NO. A liquid can’t be compressed because the space between the particles is too small. </li></ul>
  5. 5. Particles vs. Substances <ul><li>Particles are the smallest piece of a substance that is still that substance. A substance is made up of many, many particles. </li></ul>
  6. 6. Was Owen right? <ul><li>Owen was correct when he said all 6 chemicals were substances because each of them was a unique form of matter and different from the others </li></ul>
  7. 7. X X X Is Matter X Particles have high kinetic energy X X X Volume can contract X X X Volume can expand X Particles have medium kinetic energy X Particles are far apart and free-floating X Particles are loosely packed together X Particles can be compressed X Particles have low kinetic energy X Particles are tightly bonded and close together Gas Liquid Solid Characteristic
