Definitions
| Term | Definition |
|---|---|
| Thermal Energy | the sum of the kinetic energy and the potential energy of the particles that make up a material |
| Temperature | represents the average kinetic energy of the particles that make up a material |
| Heat | is the movement of thermal energy from a warmer object to a cooler object |
| Radiation | the transfer of thermal energy from one material to another by electromagnetic waves |
| Conduction | the transfer of thermal energy between materials by the collisions of particles |
| Thermal conductors | material through which thermal energy flows easily. |
| Thermal insulators | material through which thermal energy does not flow easily |
| Specific Heat | amount of thermal energy required to increase the temperature of 1 kg of a material by 1 degrees Celsius |
| Thermal Contraction | is a decrease in a materials volume when its temperature decreases. |
| Thermal Expansion | is a increase in a materials volume when its temperature increases. |
| Convection | is the transfer of thermal energy by the movement of particles from one part of a material to another. |
| Convection Currents | movement of fluids in a cycle because of convection |
| Heating Appliance | a device that converts electric energy into thermal energy |
| Thermostat | a device that regulates the temperature of a system |
| Refrigerator | device that uses electric energy to transfer thermal energy from a cooler location to a warmer location. |
| Heat Engine | a machine that converts thermal energy into mechanical energy. |
