Answer 1

A light bulb changes the chemical energy of the bulb into electromagnetic radiation, or light. Which in return gets transformed into heat

Answer 2

@rushwr what about the second one? c:

Answer 3

Wait still reading

Answer 4

wood is a store of chemical energy. As it burns in the fireplace, chemical energy is released and converted to thermal energy (heat) and light energy.

Answer 5

Okay, so the same? @rushwr

Answer 6

That's what I thought too . @paki What do u think of this ?
