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 |
