| 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 a cooler material. |
| thermal energy | sum of the kinetic and potential energy of the articles in an 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 1*C. |
| 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 form one place to another. |
| radiation | transfer 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 | study of the relationship between thermal energy, heat, and work. |
| first law thermodynamics | states that the increase in thermal energy of a system equals the work done on the system plus the heat added to the system. |
| heat engine | device that converts thermal energy into work. |
| internal combustion engine | heat engine that burns fuel inside the engine in chambers or cylinders. |
