1. Units: g/mL, g/cm3

2. Energy

3. the part of the universe under consideration
SYSTEM
the part of the universe under consideration
(ex. An atom or a beaker with chemicals)

4. Energy in a reaction is released (gets hot)
EXOTHERMIC
Energy in a reaction is released (gets hot)

6. Energy in a reaction is absorbed (gets cold)
ENDOTHERMIC
Energy in a reaction is absorbed (gets cold)

8. Energy transferred as a result of a temperature difference
HEAT
Energy transferred as a result of a temperature difference
(Symbol = q)

9. JOULE
SI unit on energy
(Symbol = J)

10. Specific Heat (Cp)
The heat required to raise the temperature of 1 gram of substance by 1°C.
Unit = J / (g)(°C)

11. Every material has its own specific heat (see Appendix Table A-3)

12. q = (m)(ΔT)(Cp)
Heat lost or gained = mass * change in temp * specific heat of a substance
