Thermochemisty

1. quantity of heat needed to vaporize a mole of a certain liquid; intensive property
3. the q absorbed by 1 mole of a solid substance as it changes states from solid to liquid at a constant temperature
4. piece of equipment used to measure the heat of reactions; able to obtain change in temperature from a reaction; a container that is insulated with thick walls, therefore able to keep heat
5. Type of reaction where q flows out of the system and into the surroundings; Negative "q".
7. the vessel for the system in a reaction such as a beaker
12. Balanced stoich equation with the energy change
14. quantity of q necessary to increase the temperature of 1 gram of water by 1 degree Celsius; 1kcal = 1 Cal
16. the amount equal to the entire q; H=E+PV
18. The amount of q needed to increase the temperature of an object by 1 degree Celsius based on the mass of the object

2. the study of energy transformation that happens during a change in state or chemical reaction
6. the science that measures the amount of heat transferred during a reaction, uses calorimeter to measure change in temperature
8. the portion of heat needed to grow the temperature of 1 g by 1 degree Celsius; thermal inertia
9. metric system unit for energy
10. Also known as enthalpy dissolution
11. The reaction where heat is absorbed into the system; positive "q"
13. Ability to supply q or do work
15. focal point, the substance that undergoes a physical or chemical change, the reaction
17. energy that is moved from a hot object to a colder one from a difference in temperature; All of the P.E. and K.E. that can be used to increase temperature or do work in a system.
