How are conduction, convection and radiation similar? | They all transfer heat. |
How are conduction, convection and radiation different? | Each has a different method of transferring heat. |
Provide an example of conduction. | Touching a hot pan. |
Provide an example of convection. | Hot air balloon rising as warm air beneath it rises. |
Provide an example of radiation. | Feeling warmth from sunlight. |
Explain the difference between good conductors and poor conductors (insulators)? | Good conductors, like metal, pass heat quickly and efficiently. Insulators, like styrofoam and wool, do not. |
