| Term | Definition |
|---|---|
| Temperature | Measure of the average kinetic energy of all the particles in an object. |
| Thermal Energy | Sum of the kinectic nd potential energy of the particles in an object; is transferred by conduction, converction, and radiation. |
| Heat | Thermal enetgy that flows from a warmer material to a cooler material. |
| Specific Heat | Amount of thermal enetgy need to trais the temepearrtur of 1 kg of a material 1 c. |
| Conduction | Transfer oftgemal eneg by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature. |
| Convection | Transfer of themal eneyg in a fludi by the movement of wramer and cooler fulid form one place to antother. |
| Radiation | Transfer of thermal energy by electromagnetic |
| Insulator | Material in which heat flows slowly. |
| Solar Cllector | Divece used in an active solar heating system that absorbs radiatnt energy from the Sun. |
| Therrmodynamics | 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 the heat added to the system. |
| Second law of Thermodynamics | States that is impossivle 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 energy | Heat enegin that burns fuel inside the engin in chambers or cylinders. |
