  1. 3. The change of state from a solid to a gas.
  2. 6. Everything that has mass and takes up space.
  3. 10. The transfer of heat energy in the form of waves.
  4. 11. A state of matter that has a defined shape and volume. The particles vibrate back and forth and are locked in place.
  5. 14. The change in state from plasma to gas.
  6. 15. The coldest temperature, 0 Kelvin, that can be reached. It is the hypothetical temperature at which all molecular motion stops.
  7. 17. Small pieces of matter.
  8. 20. Another name for heat energy.
  9. 21. A state of matter with no defined shape or volume. The particles move with a high amount of energy and spread as far apart as possible.
  10. 22. The temperature at which a solid becomes a liquid.
  11. 23. The change in state from gas to plasma
  12. 24. The direct transfer of heat from one object to another through direct touch.
  13. 26. The change in state from a solid to a liquid.
  14. 27. Vaporization that occurs only at the surface of a liquid.

  1. 1. The physical forms of matter, which include solid, liquid, gas, and plasma.
  2. 2. The change of state from a liquid to a gas.
  3. 4. A change from one state of matter to another.
  4. 5. Vaporization that occurs throughout a liquid.
  5. 7. The temperature at which a liquid changes into a solid.
  6. 8. A state of matter that has no defined shape but has a defined volume. The particles flow past each other with a medium amount of energy.
  7. 9. The temperature at which a liquid changes to a gas.
  8. 12. The change of state from a liquid to a solid.
  9. 13. Process by which, in a liquid or gas being heated, the warmer part of the mass will rise and the cooler portions will sink.
  10. 16. A state of matter that is a superheated gas with electrons.
  11. 18. The change of state from a gas to a liquid.
  12. 19. The change of state from a gas to a solid.
  13. 25. Another word for heat.
