  1. 2. The ability to do work, there are two kinds
  2. 3. A solid substance seems to "shrink and disappear", a solid substance turns into a vapor without becoming a liquid first.
  3. 5. Solid becomes a liquid
  4. 9. Opposite of vaporization, where gas becomes becomes liquid water.
  5. 10. Anything that occupies space and time
  6. 13. The liquid forms bubbles that rise through the liquid.
  7. 16. Liquid becomes a gas
  8. 17. These particles can move around but are still close together. They do not have a fixed shape
  9. 20. These particles are far apart and move very fast. Have almost no attraction for each other
  10. 21. Occurs at any temperature between the melting point and the boiling point of the liquid.
  11. 24. of matter solid, liquid, gas
  12. 26. change A type of change in matter when it doesn't change its chemical identity
  13. 28. The atoms of one element can bond with atoms from other elements to form this
  14. 29. Exerted by matter on other matter. The earth exerts a gravitational force on everything on its surface and near it in space. For a geologist, this is probably the most important field force he deals with. Gives things weight.

  1. 1. A vapor substance seems to "appear out of nowhere", a vapor turns into a solid substance without becoming a liquid first.
  2. 4. Distinct particles formed by the combination of two or more atoms
  3. 6. Atoms that have more or less electrons than protons. This creates atoms with negative or positive charges, due to the difference in electrons.
  4. 7. Particles slow down until their attraction to each other locks them into fixed positions. Also known as solidification
  5. 8. law of Thermodynamics Energy and matter cannot be created or destroyed, it can only change shape
  6. 11. A measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object.
  7. 12. Combination of two or more pure substances
  8. 14. Smallest building block of matter. Have a nucleus, protons, neutrons, and electrons. The same number of electrons and protons
  9. 15. A Push or Pull
  10. 18. The attraction between particles is greater than their ability to move away from each other. Their particles vibrate in a fixed place
  11. 19. a force that acts on an object as it moves through a distance
  12. 22. Particles move very fast and collide very hard that they break apart and become electrically charged.
  13. 23. The effect of gravity on an object.
  14. 25. The amount of matter in an object.
  15. 27. Change When a substance changes into another substance
