| Term | Definition |
|---|---|
| Temperature | measure of the average kinetic energy of all the particles in an object |
| Heat | thermal energy that flows from a warmer material to cooler material |
| Thermal Energy | sum of the kinetic and potential energy of the particles in n object; is transferred by conduction, convection, and radiation |
| Specific Heat | amount of thermal energy needed to raise the temperature of 1 kg of a material 1C |
| Conduction | transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature |
| Convection | transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from on place to another |
| Radiation | transfer of thermal energy by electromagnetic waves |
| Insulator | material in which heat flows slowly |
| Solar Collector | device used in an active solar heating system that absorbs radiant energy from the Sun |
| Thermodynamics | study of the relationship between thermal energy, heat, and work |
| First Law of Thermodynamics | states that the increase in thermal energy of a system equal the work done on the system plus the head added to the system |
| Second Law of Thermodynamics | states that is impossible for heat to flow from a cool object to a warmer object unless work is done |
| Heat Engine | device that converts thermal energy into work |
| Internal Combustion Engine | heat engine that burns fuel inside the engine in chambers or cylinders |
