Across
  1. 2. A substance that changes phases when its energy increases or decreases
  2. 7. This phase change turns a gas into a liquid and releases energy
  3. 8. This takes place only at the surface, and the molecules absorb surface energy
  4. 9. A reaction that takes place and forms a new substance
Down
  1. 1. this phase chance goes for a liquid into a gas, and absorbs energy
  2. 3. this phase change goes form a solid straight to a gas and release energy
  3. 4. this phase change happens throughout the entire substance because it is being heated
  4. 5. this phase change starts as a liquid and freezes into a solid, and releases energy
  5. 6. This phase change Absorbs energy,and goes from a solid to a liquid
