A student builds an electrical circuit. In the circuit, a battery is connected to a siren.

Which series of energy transformations takes place in the circuit when the
siren turns on?

A. Chemical energy - Sound energy - Electrical energy

O B. Electrical energy - Chemical energy - Sound energy

C. Chemical energy - Electrical energy - Sound energy

O D. Sound energy - Electrical energy - Chemical energy

C. Chemical energy - Electrical energy - Sound energy

Explanation:

According to the law of conservation of energy, energy can be transformed i.e changed from one form to another. According to this question, a student builds an electrical circuit, which connects a battery to a siren. Based on this description, the electrical circuit uses ELECTRICAL ENERGY supplied by the CHEMICAL ENERGY in the battery cell.

The electrical energy in the circuit connects the CHEMICAL ENERGY in the battery to the siren, which makes the sound using SOUND ENERGY. In other words, the CHEMICAL ENERGY of the battery powers the ELECTRICAL ENERGY of the circuit to make SOUND ENERGY in the siren. Hence, the order of energy transformation is: Chemical energy - Electrical energy - Sound energy
