Which particles cannot move from their place?

The correct answer is Solid particles. In the solid state of matter, particles are tightly packed together in fixed positions. While they vibrate, they do not have the freedom to move or slide past one another from their designated places, which gives solids their definite shape and volume.

• Gas particles move freely and randomly, occupying the entire volume of their container.
• Liquid particles are close together but can slide past each other, allowing liquids to flow and take the shape of their container.
• Plasma particles are highly energetic, ionized gas particles that move freely and are not confined to fixed positions.
