Answer:
Conduction
- A warm can... (direct contact leads to heat transfer)
- An egg begins... (key words = makes contact)
- A girl's bare... (direct contact leads to heat transfer)
Convection
- A hot air balloon... (key words = hot air rises)
Radiation
- A boy's shirt... (indirect contact with sun's rays)
- A heater blows... (indirect contact with hot air)
Step-by-step explanation:
Here is my cheat sheet to remembering what is what:
- Conduction = direct transfer of heat (think of touching a hot pan)
- Convection = hot air rises and cool air sinks (think of water cycle)
- Radiation = indirect transfer of heat (think of the sun)
I hope this helps!
