Answer 3

Conduction: Is a heat transfer that occurs when the objects are in contact.
Example: Pretend we have a hot saucepan. The pan is in contact with the handle right? Heat will transfer into the handle as well as the pan hence that they are in interact. This is an example of conduction on a saucepan.

Answer 4

Convection:
Is the process of heat transfer that occurs when warm particles move in currents.

Say that we put water in the saucepan and started to boil it. Water particles nearby the bottom is heated the most. When it heats, it becomes less dense. Then the heated H2O escalates upwards to the top of the saucepan.

Answer 5

Radiation:


Radiation travels through space to a matter.

“Does anyone know where the saucepan is?”
I called as I rummaged through the camping supply. Then there I saw it, my baby cousin had it. Sucking on the handle like her favorite pacifier… Yeah!
“Hey there Suzy! Want to give you favorite cousin her saucepan back so we could make dinner?”
She looked at me like I was growing two heads. Three, actually. That is when that brat of a cousin started throwing a fit.
I sighed.
This is going to take a while….
- After math –
After I washed all of the revolting drool of my pan, I put fresh, new water in it. Then I boiled it over the camp wood fire. As I glanced around I noticed my Aunt Katy taking care of little Suzy, who was glaring at me. I guess I am not her favorite anymore. ‘Well, this would change her tune,’ I hummed as I dumped a box of macaroni in the pot. Marconi and cheese is her favorite food; and I do make some good Marconi and cheese.

Answer 6

(when the narrator boiled the pan under a stove, that is how it reflected radiation)
