1. calorie (cal) unit of heat or other energy; the
amount of energy required to
raise 1 gram of water by 1 degree
Celsius; 1 cal is defined as 4.184 J
2. endothermic process chemical reaction or physical
change that absorbs heat
3. energy the capacity to supply heat or do
work
4. exothermic process chemical reaction or physical
change that releases heat
5. joule (J) SI unit of energy; 1 joule is the
kinetic energy of an object with a
mass of 2kg moving with a veloc-
ity of 1 m/s, 1 J = 1 kg m2/s and
4.184 J = 1 cal
6. kinetic energy energy of a moving body, in
joules, equal to 1/2mv^2
7. potential energy energy of a particle or system
of particles derived from relative
position, composition, or condi-
tion
8. thermal energy kinetic energy associated with the
random movement of atoms or
molecules
9. thermochemistry

study of measuring the amount
of heat absorbed or released
during a chemical reaction or a
physical change
10. which of the following substances would you ex- Wood, gasoline, hydrogen gas
pect to have a relatively high chemical potential
energy: Wood, Gasoline, Chalk, Water, Hydrogen
Gas?
11. heat (q) transfer of thermal energy be-
tween two substances
12. surroundings all matter other than the system
being studied
13. system portion of matter undergoing a
chemical or physical change be-
ing studied
14. temperature intensive property of matter that
is a quantitative measure of "hot-
ness" and "coldness"
15. When 50.0 mL of 0.10 M HCl(aq) and 50.0 mL of Lesser; more heat would be lost
0.10 M NaOH(aq), both at 22.0 °C, are added to to the coffee cup and the envi-

we used a calorimeter that was a poorer insulator
than a coffee cup calorimeter? Explain your an-
