What are the three fundamental states of matter?

• A. Plasma, solids, liquids.
• B. Solids, liquids, and gases.
• C. Liquids, gases, plasma.
• D. Bose-Einstein condensate, liquids, solids.

Answer: (B)

Matter exists in three common forms because of how particles are arranged and move: in a solid, particles are tightly packed and vibrate in place, giving a definite shape and volume; in a liquid, particles are looser, so they flow and take the shape of their container while keeping a definite volume; in a gas, particles are far apart and move freely, so they fill the space and take both the shape and volume of their container. The choice that lists solids, liquids, and gases aligns with these everyday states. Plasma is also a state of matter at high energy, and Bose-Einstein condensate is a special quantum state at very low temperatures, but they aren’t the three basic states usually taught at this level. So the correct option is the one with solids, liquids, and gases.
