What kind/s of energy transfers did you notice in each scenario?

What scenario? I don't see a picture that helps me help you.

I don’t know what we’re talking about but I just wanna add this? ⬇️

For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change. Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed.
