  1. 3. Any substance that can flow.
  2. 4. point The temperature at which a substance changes from a solid to a liquid.( The same as the freezing point, is a temperature at which a liquid changes to a solid.)
  3. 6. The change in state from a liquid to a solid
  4. 7. law A principle that describes the relationship between the temperature and volume of a gas at constant pressure.
  5. 9. proportional A term used to describe the relationship between two whose graph is a straight line passing through the point.
  6. 13. The change in state from a solid directly to a gas without passing through a liquid state.
  7. 14. proportional A term used to describe the relationship between two variables whose product is constant
  8. 18. solids A solid made up of particles that are not arranged in a regular pattern.
  9. 19. solid A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern.
  10. 20. law A principle that describes the relationship between the pressure and volume of a gas at constant temperature.
