Across
  1. 2. an equation that includes the quantity of energy as heat released or absorbed during the reaction as written
  2. 5. the unit used to express energy; equivalent to the amount of work done by a force of 1 N acting through a distance of 1 m in the direction of the force; abbreviation, J
  3. 8. species that appear in some steps but not in the net equation
  4. 10. a device used to measure the energy as heat absorbed or released in a chemical or physical change
  5. 11. the amount of energy released or absorbed as heat during a chemical reaction
  6. 13. the branch of chemistry that is the study of the energy changes that accompany chemical reactions and changes of state
  7. 16. the amount of energy released or absorbed as heat by a system during a process at constant pressure
  8. 17. energy is always transferred from higher-temperature objects to lower-temperature objects until thermal equilibrium is reached; the energy transferred between objects that are at different temperatures; the SI unit for this as well as all other forms of energy is joule, J.
Down
  1. 1. the energy in a system that is available for work
  2. 3. a reaction whose reactants and products exist in a single phase
  3. 4. a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object; the unit should be in kelvins
  4. 6. the energy released as heat by the complete combustion of a specific amount of a substance at constant pressure or volume
  5. 7. the amount of energy as heat resulting from the formation of 1 mol of a substance at constant pressure
  6. 9. a measure of the randomness or disorder of a system
  7. 12. the difference between the change in enthalpy, ΔH, and the product of the Kelvin temperature and the entropy change, which is defined as TΔS, at a constant pressure and temperature
  8. 14. the overall enthalpy change in a reaction is equal to the sum of the enthalpy changes for the individual steps in the process
  9. 15. the quantity of heat required to raise a unit mass of homogeneous material 1 K or 1oC in a specified way given constant pressure and volume
