Heat Transfer
Heat
| Question | Answer |
|---|---|
| Convection | The transfer of heat by the movement of FLUID. |
| Conduction | The transfer of heat from one substance to another by DIRECT CONTACT. |
| Radiation | The transfer of heat through ELECTROMAGNETIC WAVES. |
| Convection Example | Warm air rising and cool air sinking in the atmosphere OR the warm wax rising and cool wax sinking in the lava lamp |
| Radiation Example | Light bulb OR Sun |
| Conduction Example | Metal coil heating the wax OR the ground heating the air above |
| Temperature | The AVERAGE amount of energy of motion for each particle of a substance |
| Thermal Energy | The TOTAL amount of energy of motion in the particles of a substance |
| What has more thermal energy, a glass of 90 degree water or the ocean? Why? | The ocean because it has more particles. Thermal is the TOTAL amount of energy. |
| The Sun is what form of heat transfer? | Radiation |
| The ground heating the air above is what form of heat transfer? | Conduction |
| The warm air rising and cool air falling is known as a... | Convection Current |
| Gas and Liquid are both... | Fluids |
| How is heat transferred through the atmosphere? | Convection Currents |
