Question

20-point physics question! :D

Answer 1

Your hands get warm by a fire because chemical energy is converted into heat energy. 

The wood - has chemical energy when you burn it, and then, heat waves rise to the air, which means that we went from :

Chemical energy ⇒ Heat energy

Alright, now, also think about, that energy can never be created not destroyed, so it was obviously transferred, and yet conserved. 

If this doesn't make sense, please message me, or comment below. :))

Answer 2

I think, it must be a chemical. Because the fire is a chemical reaction. So, the chemical energy converted to heat energy.
