Terms | Definitions |
|---|---|
 Temperature | A measure of the average kinetic energy of the particles in a substance |
| Internal Energy | The energy of a substance to to both the random motions of its particles and to the potential energy that results from the distances and alignments between the particles. |
| Thermal equilibrium | The state in which two bodies in physical contact with each other have identical temperatures. |
| Heat | The energy transferred between objects because of a difference in their temperatures. |
| Specific Heat Capacity | The quantity of heat required to raise a unit mass of homogeneous material 1K or 1°C in a specified way given constant pressure volume. |
| Calorimetry | An experimental procedure used to measure the energy transferred from one substance to another. |
| Phase Changes | The physical change of a substance, from one state to another at a constant temperature and pressure. |
| Latent Heat | The energy per unit mass that is transferred during a phase change of a substance. |
| System | A set of particles or interacting components considered to be a distinct physical entity for the purpose of study. |
| Environment | The combination of conditions and influences outside a system that affect the behavior of the system. |
| Isovolumetric process | A thermodynamic process that takes place at constant volume so that no work is done on or by the system |
| Isothermal process | A thermodynamic process that takes place at constant temperature. |
| Adiabatic process | A thermodynamic process during which no energy is transferred to or from the system as heat. |
| Cyclic process | A thermodynamic process in which a system returns to the same conditions under which it started. |
| Entropy | A measure of the randomness or disorder of a system. |
