  1. 1. This property of matter involves numbers and finding data such as length, temperature, mass, or volume.
  2. 5. This process occurs when heat is added to a solid, changing it to a liquid. (Example: solid candle turning into liquid wax)
  3. 7. This source of heat energy involves two objects rubbing against each other, causing heat.
  4. 8. This source of heat energy involves a flame. Examples of this heat source include candles or wood.
  5. 10. In order for matter to change states, this must increase or decrease.
  6. 14. This SLOW process occurs when heat is added to a liquid, changing it to a gas. (Example: After a rainstorm in the summer, a puddle will slowly turn into a gas due to the heat from the sun.)
  7. 15. A state of matter with no definite volume or shape
  8. 17. This process occurs when heat is removed from a gas, changing it to a liquid. (Example: water droplets on the outside of a cup)

  1. 2. A state of matter with a definite volume, but no definite shape
  2. 3. There are 3 _________ of matter.
  3. 4. This process occurs when heat is removed from a liquid, changing it to a solid. (Example: water to ice)
  4. 6. When this is used, heat energy is produced. Examples of this heat source include lamps, TV's, and stoves.
  5. 9. By _________ heat energy, a gas can change to a liquid and a liquid can change to a solid.
  6. 11. Anything that has mass and takes up space
  7. 12. This property of matter involves descriptions and uses your five senses.
  8. 13. This FAST process occurs when heat is added to a liquid, changing it to a gas. (Example: When cooking, water is often heated quickly, causing it to bubble and produce steam.)
  9. 16. By _________ heat energy, a solid can change to a liquid and a liquid can change to a gas.
  10. 18. A state of matter with a definite size and shape
