The spark produced when a person touches the door knob after walking is due to the conversion of the mechanical energy into the electrical energy.
Explanation:
The law of conservation of energy states that the energy can neither be created nor be destroyed. It can only be converted from one form to another by means of suitable devices as per the requirements.
The amount of energy present in a body is due to the food taken by the body and it is stored in the form of the chemical energy of the food. The body converts the energy into various forms as per the requirements of the various organs of the body.
As the person walks across the room, the chemical energy of the food first gets converted into the mechanical energy. When the person touches the door knob, there is an electrical wave that transfers from the person to the metallic knob and a spark is observed.
Thus, The spark produced when a person touches the door knob after walking is due to the conversion of the mechanical energy into the electrical energy.
