Thermochemistry

1. Energy Energy due to motion
5. Study of energy transfer in the form of heat during chemical reactions and physical changes
7. Unit of work or energy
9. Energy transferred because of molecular movement that deals with the amount and type of molecules
10. The internal energy of the system
11. Reaction that releases heat and feels cold
12. of Conservation of Energy Law that you cannot destroy or create energy
14. Energy released as heat by combustion of a specific amount of a substance at constant pressure or volume
17. Science or act of measuring changes in chemical reactions
18. Potential Energy Form of potential energy that can be absorbed or released during a chemical reaction
19. Energy Stored energy

2. Device used to measure the energy as heat absorbed or released in chemical/physical change
3. heat The quantity of heat required to raise a unit mass of homogeneous material 1 degree Celsius
4. Amount of heat absorbed in the transformation of the reactants at given temperature and pressure
6. Amount of energy as heat required to change 1 molecule of substance from solid to liquid
8. Amount of energy as heat required to convert liquid to gas
13. Unit of energy needed to increase the temperature by 1 degree
14. Reaction that absorbs heat and feels hot
15. Measure of molecular movement
16. Ability to do work
