| Term | Definition |
|---|---|
| Temperature | measure of the average kinetic energy of all the particles in an object |
| thermal energy | sum of the kinetic and potential energy of the particles in an object, is transferred by conduction, convection,and radiation |
| heat | thermal energy that flows from a warmer material to a cooler material |
| specific energy | amount of thermal energy needed to raise the temperature of 1kg 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 one place to another |
| radiation | transfers of thermal energy by electromagnetic waves |
| insulator | material in which electrons are not able to move easily |
| solar collector | device used in an active solar heating system that absorbs radiant energy from the sun |
| thermodynamics | the study of the relationship between thermal energy, heat,and work |
| first law of thermodynamics | states that the increase in thermal energy of a system equals the work done on the system plus heat 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 |
