Knocking a nail into a wooden block with a hammer involves conversion between different forms of energy, which of the following choices present this conversion in correct order.

1. chemical energy → gravitational potential energy → kinetic energy → (sound energy + heat energy)
2. chemical energy → kinetic energy → gravitational potential energy → (sound energy + heat energy)
3. chemical energy → (sound energy + heat energy) → kinetic energy → gravitational potential energy
4. (sound energy + heat energy) → chemical energy → kinetic energy → gravitational potential energy
