| Term | Definition |
|---|---|
| Law of Conservation of Energy | Energy can neither be created nor destroyed. |
| Chemical Thermodynamics | The area of Chemistry that deals with applying thermodynamic principles to energy changes in chemical reactions. |
| Potential Energy | The energy associated with the position of an object relative to a force upon it. |
| Kinetic Energy | The energy associated with motion. |
| System | The sample of matter being studied. |
| Surroundings | The remainder of the universe. |
| Internal Energy | The sum of all the possible forms of energy of all ions, atoms, and molecules in a system. |
| State Function | Its value is determined only by the state of the system. |
| First Law of Thermodynamics | This law is a practical application of the Law of the Conservation of Energy. |
| Joule | The SI unit of energy and energy transfer, including work and heat. |
| Enthalpy | The internal energy plus the product of the pressure and volume. |
| Endothermic Reaction | The products are usually colder than the reactants because energy has been absorbed. |
| Exothermic Reaction | The products are usually hotter than the reactants because some energy was released as heat. |
| Energy | The ability to do work. |
