| Chemical Energy | The energy contained in the chemical bonds of a substance. |
| Conduction | Direct movement of energy from one molecule to the next |
| Convection cell | Circular movements of fluids due to changes in density |
| Convection | The movement of fluids due to differences in density created by uneven heating |
| Direct Current | Electrical current that moves in one direction. |
| Electrical Energy | A form of energy that is produced by the flow of electric charge through a conductor. |
