PLZ HELP!! IM DESPERATE, ASAP IF YOU CAN!


The steps in the heating of the handle of a pan held over a flame are listed below:

Step 1: Heat from the flame travels to the base of the pan
Step 2: Heat from the base of the pan travels through the pan to the part where the handle touches the pan
Step 3: Heat from one end of the handle travels to the other end

By which method is heat transferred in the three steps?

Radiation in Step 1 and conduction in Steps 2 and 3
Conduction in Step 1 and radiation in Steps 2 and 3
Conduction in Step 1 and convection in Steps 2 and 3
Convection in Step 1 and conduction in Steps 2 and 3

Your most likely answer would be D, though, I'm not too sure on it.

However, conduction is present during this process, as well for convection. Convection started up the heating process, and it caused conduction within the pan.


I'm hoping this helps you out.

Answer:

Convection in Step 1 and conduction in Steps 2 and 3

Explanation:

Convection is the fire and the clue word that led me to conduction for steps 2/3 is "touches" it was either Radiation in Step 1 and conduction in Steps 2 and 3 OR Convection in Step 1 and conduction in Steps 2 and 3 and it is not radiation because there is no electromagnetic waves in the flame so its Convection in Step 1 and conduction in Steps 2 and 3, THE LAST ONE, D
