Across
  1. 2. : System releases heat (deltaQ<0)
  2. 4. LAW : Energy spontaneously disperses from being localized to becoming spread out if it is not hindered from doing so
  3. 7. DIAGRAMS : Graphs that show the temperatures and pressures at which a substance will be thermodynamically stable in a particular phase
  4. 10. : The measure of the spontaneous dispersal of energy at a specific temperature: how much energy is spread out, or how widely spread out energy becomes
  5. 11. : Experience no change in volume
  6. 13. SYSTEM : The system cannot exchange energy (heat and work) or matter with the surroundings; for example an insulated bomb calorimeter
  7. 14. LAW : Implies that objects are in thermal equilibrium only when their temperatures are equal
  8. 15. : Occur when no heat is exchanged between the system and the environment; thus, the thermal energy of the system is constant through the process
  9. 16. : The process of measuring transferred heat
  10. 17. POINT : Phase boundary that separates the solid and liquid phases terminates at a point called the critical point
  11. 19. LAW : Energy cannot be created or destroyed, only converted from one form to another
Down
  1. 1. LAW : States that enthalpy changes of reactions are additive
  2. 3. : Liquid to solid
  3. 5. : The ability to do work
  4. 6. : Study of energy changes involved in physical and chemical changes
  5. 8. : A specific type of vaporization that occurs only under certain conditions
  6. 9. : The pressure of the system is constant
  7. 10. : Processes in which systems absorb heat; delta Q >0
  8. 12. : Equivalent to heat (Q) under constant pressure
  9. 18. SYSTEM : Exchange of energy, not matter
