Which of the following are the three physical states of matter?

The three physical states of matter are solid, liquid, and gas. In solids, particles are closely packed together, allowing them to maintain a fixed shape and volume. In liquids, particles are still close but can move around each other, providing a definite volume while taking the shape of their container. Gases have particles that are far apart and can move freely, resulting in no fixed shape or volume, expanding to fill any available space.

While options that mention plasma, vapor, or different combinations may include states of matter, solid, liquid, and gas represent the most commonly recognized and foundational states in basic physical science. This foundational understanding is crucial for further studies in thermodynamics and various scientific applications involving matter.
