| Term | Definition |
|---|---|
| What is Thermal Energy? | The sum of kinetic energy and potential energy of the particles that make up a material. |
| What is Temperature? | Represents the average kinetic energy of the particles that make up a material. |
| How are temperature and kinetic energy related? | The average kinetic energy of the particles that make up a material is the temperature of the material. |
| What happens when the liquid in a thermometer moves? | When the alcohol increases, the temperature rises and when the alcohol decreases, the temperature falls. |
| What is Heat? | The movement of thermal energy from a warmer object to a cooler object. |
| What way does Thermal energy move? | Moves from the conductor (Metal) to the insulator (Non Metal) |
| 3 types of thermal energy transfer | Radiation, Conduction, and Convection. |
| What is Radiation? | The transfer of thermal energy from one material to another by waves. (Waves) |
| What is Conduction? | The transfer of thermal energy between materials by the collision of particles. (Touching) |
| What is Convection? | The transfer of thermal energy by the movement of particles from one part of the material to another. (Heat rises) |
| What is thermal expansion and contraction? | Particles are spread out as their kinetic energy increases.Thermal contraction occurs because particles get closer together as their kinetic energy decreases. |
| What is a heating appliance? | Is a device that converts electric energy into thermal energy. |
| Does a Refrigerator transfer thermal energy? | Yes. It transfers thermal energy from a warmer area to a cooler area. |
