| Question | Answer |
|---|---|
| Measure of the average kinetic energy of all the particles in an object. | Temperature |
| Thermal energy that flows from a warmer material to a cooler material. | Heat |
| Sum of the kinetic and potential energy of the particles in an object; is transferred by conduction, convection, and radiation. | Thermal Energy |
| Amount of thermal energy needed to raise temperature of 1kg of a material 1 Celsius. | Specific Heat |
| Transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature. | Conduction |
| Transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another. | Convection |
| Transfer of energy by electromagnetic waves. | Radiation |
| Material in which heat flows slowly. | Insulator |
| Device used in an active solar heating system that absorbs radiant energy from the Sun. | Solar Collector |
| Study of the relationship between thermal energy, heat, and work. | Thermodynamics |
| States that the increase in thermal energy of a system equal the work done on the system plus the heat added to the system. | First Law of Thermodynamics |
| States that it is impossible for heat to flow from a cool object to a warmer object unless work is done. | Second Law of Thermodynamics |
| Device that converts thermal energy into work. | Heat Engine |
| Heat engine that burns fuel inside the engine in chambers or cylinders. | Internal Combustion Engine |
