Thermochemistry

3. symbolized as △H: same as the heat content at a constant pressure
4. device used to measure heat being absorbed or released
5. equal to the heat flow at constant pressure
8. complete burning of one mole of a substance which is the heat is the reaction
9. energy neither created or destroyed
12. amount of heat needed to vaporize of a liquid
14. energy that is stored
15. heat is neither released or absorbed
16. rest of universe
17. metals get hot quicker than water because it has a lower
19. is numerically the same as the molar heat of vaporization

1. heat absorbed as solid melts to liquid
2. heat released by a system will eventually be even with the heat absorbed by its surroundings
3. If you want your hands to cool down from being too hot, you should put your hands around this reaction in a flask.
6. chemical equation that includes enthalpy change
7. heat lost when liquid solidifies
10. If my hands are cold, I should put them around a flask with this reaction taking place
11. energy that occurs during chemical reactions and changes in phases
13. is represented by “q” and ALWAYS flows from a warmer object to cooler object
17. individual focuses their attention
18. depends on both the object's mass and chemical composition
