| A | B |
| 1st law of thermodynamics | energy can neither be created or consumed |
| calorimeter | insulated container to measure change in temperature |
| heat capacity | amount of energy needed to raise temp. 1 deg. C |
| specific heat capacity | amount of energy neeeded to raise 1g of substance by 1 deg. C |
| enthalpy (H) | equal to the heat energy transferred at constant pressure |
| entropy (S) | measure of disorder or positional possibilities |
| 2nd law of thermodynamics | entropy of the universe is constantly increasing |
| 3rd law of thermodynamics | the entropy of a pure, perfectly formed crystalline substance at absolute zero is zero |
| Gibbs Free Energy (G) | can be used to determine if a reaction will be spontaneous |
| k | thermodynamic equilibrium constant |
