Answer 1

Light is the answer

Answer 2

Answer:

d

Explanation:

a.But, like solids and liquids, air is matter. It has weight (more than we might imagine), it takes up space, and it is composed of particles too small and too spread apart to see. Air, a mixture of gases, shares properties with water vapor, the gaseous form of water that is part of air.

b.Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Gold is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. ... For additional facts and information refer to Gold Properties.

c.Your house, the food you eat, and even your dog are matter. Matter is usually found in three forms, or states. The three states of matter are gas, liquid, and solid. All matter is made of tiny parts called atoms.

d.Light is a form of energy, not matter. Matter is made up of atoms. Light is actually electromagnetic radiation. Moving electric charge or moving electrons (electric current) cause a magnetic field, and a changing magnetic field creates an electric current or electric field.
