What are the three common physical states of matter?

Answer and explanation

Correct answer: Solid, liquid, gas

The governing concept is the physical state of matter, which describes how particles are arranged and how freely they move under given conditions. In a solid, particles are closely packed and mainly vibrate about fixed positions, so the substance has a definite shape and volume. In a liquid, particles remain close but can flow, giving a definite volume and no fixed shape. In a gas, particles are far apart and move freely, so it has neither a fixed shape nor a fixed volume. Therefore, option A—solid, liquid, and gas—is correct. Metals, non-metals, and metalloids classify elements, while elements, compounds, mixtures and acids, bases, salts are different chemical classifications.
