1. Temperature is the average KE whereas the heat is total energy of all the particles in the substance.

2. Minimum amount of energy for a set of reactants to form a set of products.

3. PEr > PEp in an exothermic reaction

4. Vapor

5. Will discuss in class

6. there is no energy, 0K (no movement energy), pure crystal/substance (no Entropy energy)

7. randomness or disorder.

8. release

9. temperature

10. J and cal, 4.18J=1.00cal

11. Absolute temp scale bases does not change (only one condition for absolute zero) but relative temp scale basis (FP / BP water) does change (as you change pressure).

12. cal / (g degC), cal . They are not same things

13. 68 gals
14. 36.8%
15. deltaH = (m) (deltaT) (c) , deltaT = TF - TI
16.18.4 kcal
17. 110g
18. 0.19 cal / (g degC)
