검증된 단계별 안내1
Understand the three common phases of matter: solid, liquid, and gas, and also consider plasma as an ionized state of matter.
Recall that in solids, molecules are held rigidly together in a fixed, orderly arrangement, which gives solids a definite shape and volume.
In liquids, molecules are close but can move past each other, allowing liquids to flow and take the shape of their container.
In gases, molecules are far apart and move freely, filling the entire volume of their container.
Plasma consists of ionized gas with free electrons and ions, and its particles are not rigidly held together but move independently.
