Consider that the room is a closed system. ryan uses the chemical energy in his muscles to create the energy of motion. he uses this energy of motion to pull the string on the clapper of a bell to produce a sound. sound fills the room. which describes the energy in this room?

There are quite a few sources of energy being displayed in the room. First chemical energy, then mechanical energy, and finally sound energy. Despite the number of transformations happening, the total energy content remains the same. This is due to the law of conservation of energy which states that energy cannot be created nor destroyed. It can only be transformed from one form to another.

Are there options for this?
