Across
  1. 1. The specific portion of matter or space being studied to determine if heat is moving in or out
  2. 5. The standard unit of energy in the International System of Units
  3. 10. A process that releases energy to the surroundings. In these reactions, the temperature of the surroundings increases
  4. 11. A state where two objects in contact have reached the same temperature and no longer exchange heat
  5. 12. The SI unit of temperature used in science
  6. 13. A process that absorbs energy from the surroundings. In these reactions, the temperature of the surroundings decreases
  7. 16. The rule that energy cannot be created or destroyed
Down
  1. 2. The total heat content of a system
  2. 3. The theoretical lowest possible temperature, where all molecular motion stops
  3. 4. The principle that the total energy of an isolated system remains constant; it is only transformed from one form to another
  4. 6. A balanced chemical equation that includes the amount of heat energy absorbed or released
  5. 7. The amount of heat required to raise the temperature of 1 gram of a substance by 1°C
  6. 8. Reaction A process where chemical bonds in reactants are broken and new bonds in products are formed, resulting in a change in energy
  7. 9. The transfer of this energy from a warmer object to a cooler object due to a temperature difference
  8. 14. Energy transfer that occurs when a force moves an object
  9. 15. A measure of the disorder, randomness, or "spread-out-ness" of energy in a system
  10. 17. The capacity to do work or produce heat; it can change forms, but cannot be created or destroyed
