  3. 9. When the weight of an object is greater than the buoyant force or when an object is more dense than the material it is in it will ________.
  4. 11. a fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors.
  5. 12. An SI unit of pressure which equals 1 Newton exerted over an area of one square meter (1 N/m²)
  6. 16. A substance that flows; liquid or gas.
  7. 17. The process by which a gas changes to a liquid.
  8. 18. The process of changing from a solid to gas.
  9. 19. Freezing and condensation require energy to be ______________ from a substance in order to occur.
  10. 20. Devices based on Pascal's Principle that can be used to lift, move, or stop extremely heavy objects.
  11. 21. a theory explaining the states of matter, based on the concept that all matter consists of tiny particles that are in constant motion
  12. 22. An upward force that keeps an object immersed in or floating on a fluid.
  13. 24. The law of conservation of _________ states that energy cannot be created or destroyed, it can only be transformed from 1 form to another.

  1. 1. A law that states the fluids in closed containers exert pressures evenly in all directions.
  2. 2. A measure of the average kinetic energy of the particles in an object.; this does not change in a substance that is changing its state.
  3. 3. The temperature or point at which a liquid becomes a solid; 0° C for H₂O.
  4. 5. A form of matter that has a definite shape and volume.
  5. 6. The temperature at which a solid becomes a liquid; 0° C for H₂O.
  6. 8. The change in state from a liquid to a gas.
  7. 10. The law of conservation of _________ states that matter cannot be created or destroyed, it can only be transformed from 1 form to another.
  8. 13. A state of matter with no definite shape or volume.
  9. 14. A state of matter that has no definite shape but has a definite volume.
  10. 15. The resistance of a gas or liquid to flow.
  11. 23. The SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second (Kg∙m/s²).
