chapter 6 vocabulary for science
| 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 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 from one 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. |
| 1st Law of 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. |
| 2nd 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. |
