Thermal Energy
Chapter 6
| 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, comvvection, 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. |
| Conduction | Transfer of thermal energy by collisions between particles in matter at a higher 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. |
| First Law of Thermodynaics | States that the increase in thermal energy of a system equals the work done on the system plus the heat added to the system. |
| Second Law of Thermodynaics | States taht 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. |
