Electricity is not matter because it does not__________

1. Conduct

2. Occupy space or have mass

3. Form energy

4. Transfer heat

The correct answer is: Occupy space or have mass

Electricity is defined as a form of energy resulting from the existence of charged particles such as electrons or protons. The fundamental distinction that makes electricity not considered matter is that it does not occupy space or have mass. Matter is characterized by having both volume and mass; it exists in solid, liquid, or gaseous states. Electricity, on the other hand, is a flow of energy through a conductive medium and does not have the tangible qualities that define matter. It cannot be contained or measured in terms of volume in the same way that solid objects can be. Therefore, the understanding of electricity as a form of energy rather than a physical substance further underscores its nature as non-matter. Other concepts like conduction, energy formation, or heat transfer pertain to the properties and behaviors of electricity and matter but do not define what makes something matter in the first place.
