What is the relationship between air, water, and a chair?

Air and water are both essential elements for life, as humans and many other living organisms require both to survive. A chair, on the other hand, is an inanimate object used for sitting or resting. There is no direct relationship between air, water, and a chair, other than the fact that all three can be found in a typical indoor environment.

Air, water, and a chair are all matter. Matter is anything that has mass and takes up space. Air is a gas, water is a liquid, and a chair is a solid. All matter is made up of atoms, which are tiny particles that are too small to see. Atoms are made up of even smaller particles called protons, neutrons, and electrons.
