| Question | Answer |
|---|---|
| Temperature | A measure of the average kinetic energy of the particles in the object. |
| Heat | Thermal energy that flows from something at a higher temperature to something at a lower temperature. |
| Thermal Energy | The sum of the kinetic and potential energy of all the particles in an object. |
| Specific Heat | The amount of heat that is needed to raise the temperature of 1 kg of some material by 1 degree Celsius. |
| Conduction | The transfer of thermal energy by collisions between particles in matter. |
| Convection | The transfer or thermal energy in a fluid by the movement of warmer and cooler fluid from place to place. |
| Radiation | The transfer of energy by electromagnetic waves. |
| Insulator | A material in which heat flows slowly. |
| Solar Collector | Absorb radiant energy from the Sun. |
| Thermodynamics | The study of the relationship between thermal energy, heat, and work. |
| First Law of Thermodynamics | The increase in thermal energy of a system equals the work done on the system plus the heat transferred to the system. |
| Second Law of Thermodynamics | It is impossible for heat to flow from a cool object to a warmer object unless work is done. |
| Heat Engine | A device that converts heat into work. |
| Conduction | The transfer of thermal energy by collisions between particles in matter. |
| Convection | The transfer or thermal energy in a fluid by the movement of warmer and cooler fluid from place to place. |
| Radiation | The transfer of energy by electromagnetic waves. |
| Insulator | A material in which heat flows slowly. |
| Solar Collector | A device that collects solar rays. |
| Thermodynamics | |
| First Law of Thermodynamics | |
| Heat Engine | |
| Internal Combustion Engine | In which fuel is burned inside the engine in chambers or cylinders. |
