  2. 8. A change in the state of matter of a substance
  3. 9. Transfer of thermal energy in a fluid by the movement of fluid from place to place
  4. 10. Transfer of thermal energy between colliding particles
  5. 11. Measure of how spread out energy is
  6. 13. Energy Total random kinetic energy of all the particles in a substance
  7. 14. the spontaneous transfer of energy due to temperature difference.
  8. 17. Point The temperature and pressure at which the solid, liquid, and gasses phases of a pure substance can coexist in equilibrium
  9. 18. Theory - All matter is composed of particles in motion and that the rate of motion varies directly with the temperature

  3. 3. Theoretically the lowest possible temperature. Minimal internal molecular movement.
  4. 4. _____ Law of Thermodynamics - Object A and Object B are in thermal equilibrium. Object B and Object C are in thermal equilibrium, so that means so are Object A and Object C are too.
  5. 5. Liquid to solid
  6. 7. _____ Law of Thermodynamics - Using mechanical energy, a refrigerator removes thermal energy from warmer bodies.
  7. 12. A measure of the average kinetic energy of the particles in the object
  8. 15. (Latent) Heat Of ______. Thermal energy needed to vaporize 1 kg of a liquid
  9. 16. First Law of Thermodynamics - The increase in thermal energy of a system equals the work done on the system plus the thermal energy transferred to the system

  11. 20. Equilibrium Heat flows from hot (higher energy) to cold (lower energy). Reached when 2 objects in contact are at the same temperature.
  12. 21. Gas to solid
  13. 25. _____ Law of Thermodynamics - An increase in thermal energy depends on the work done and the heat added to a system
