  1. 7. theory that views the behavior of particles based on their motion and energy of movement
  2. 11. gases in which there is no attraction between particles and no energy is lost in collisions\
  3. 12. measure of the average kinetic energy of particles in a substance. Basically, a measure of the movement of particles
  4. 16. tool used to measure temperature
  5. 17. state of matter in which the particles are packed relatively closely but can move past one another
  6. 18. state of matter in which particles are at high energies and spread out to fill their container
  7. 19. The combined gas law expresses the relationship between the pressure, volume, and absolute temperature of a fixed amount of gas for a fixed number of particles of gas
  8. 20. total energy of motion of particles in a substance
  9. 21. a measure of a quantity that can cause change
  10. 22. law that relates the pressure of a gas to its temperature at a constant volume P/T = constant

  1. 1. temperature scale based on the freezing and boiling point of water,
  2. 2. law that states that when the temperature of a given mass of confined gas is constant, the product of its pressure and volume is also constant. P x V = constant
  3. 3. state of matter in which particles are at relatively low energies and are closely packed with little movement
  4. 4. of matter one of the distinct forms in which matter can exist; three common states of matter are observable in everyday life; solid, liquid, and gas
  5. 5. amount of space a substance occupies
  6. 6. energy contained in the physical state of matter
  7. 8. spreading out of particles throughout another substance; random motion of molecules by which there is a flow of matter from a region of high concentration to a region of low concentration.
  8. 9. tiny, individual part of a substance
  9. 10. temperature scale based on absolute zero- the point at which particles have no more thermal energy
  10. 13. force exerted by particles impacting the walls of a container. Mathematically equal to Force/unit area
  11. 14. change change in physical state from gas to liquid or liquid to solid for example.
  12. 15. impacts between particles
  13. 19. law that relates the volume of gas to the temperature of the gas at a constant pressure V/T = constant
