Final answer:
The three states of matter are solids, liquids, and gases. Solid particles are more compactly arranged, liquid particles have less density, and gas particles move freely due to weak intermolecular forces.
Step-by-step explanation:
There are three states of matter namely, solids, liquids, and gases. The particles of solids are more closely packed than liquids. The particles in a gas can move around freely because there are weak intermolecular forces between them.
In solids, the particles are densely packed, maintaining a definite shape and volume. In liquids, the particles are less closely packed, allowing them to flow and take the shape of their container, but still maintaining a definite volume. Meanwhile, gas particles have significant space between them, allowing them to take both the shape and volume of their container due to the weak forces between them.
