Across
  1. 5. state of matter where molecules keep a constant volume and take the shape of their container; particles slide past each other
  2. 7. anything that has mass and takes up space; can be found in different forms
  3. 8. a change of matter from one state to another by way of losing or gaining energy
  4. 9. phase change from gas to liquid; particles slowly lose energy when contacting cool surface
  5. 10. state of matter where molecules do not keep a constant shape or volume; particles move freely past each other at high speeds
Down
  1. 1. phase change from liquid to gas; particles gain some energy when heat is added
  2. 2. phase change from solid to a gas; particles rapidly gain energy from environment
  3. 3. phase change from liquid to solid; particles lose energy and stay in fixed position
  4. 4. state of matter where molecules keep a constant shape and volume; particles are tightly packed
  5. 6. phase change from gas to solid; particles rapidly lose all energy
  6. 7. phase change from solid to liquid; particles gain energy to slip out of positions and slide around
  7. 8. state of matter that is fluid, with highly charged particles; reacts with and creates electromagnetic forces
