Chapter 5 Vocabulary
| Term | Definition |
|---|---|
| Temperature | The measure of the average kinetic energy of the particles that make up the object. |
| Thermal Energy | The sum of the kinetic energy and the potential energy of all of the particles that make up that object. |
| Heat | Energy that is transferred between objects due to a temperature difference between those objects. |
| Specific Heat | The amount of heat needed to raise the temperature of 1 kg of that material by 1 degree Celsius |
| Conduction | The transfer of thermal energy by collisions between particles that make up matter. |
| Convection | The transfer of thermal energy in a fluid by the movements of warmer and cooler fluid. |
| Radiation | The transfer of energy by electromagnetic waves, such as light and microwaves. |
| Thermal Insulator | A material through which thermal energy moves slowly. |
| Solar Collector | A device that transforms radiant energy from the Sun into thermal energy. |
| Thermodynamics | The study of the relationships between thermal energy, heat, and work. |
| First Law of Thermodynamics | States that if the mechanical energy of a system is constant, the increase in thermal energy of that system equals the sum of the thermal energy transfers into that system and the work done on that system. |
| Second Law of Thermodynamics | States that energy spontaneously spreads from regions of higher concentration to regions of lower concentration. |
| Heat Engine | A device that converts some thermal energy into mechanical energy. |
| Internal Combustion Engine | A heat engine that burns fuel inside a set of cylinders. |
