Final answer:
In a solid, particles are tightly packed in a fixed position, while in a liquid, particles are close together but can move and slide past each other.
Step-by-step explanation:
The positions of particles in a solid compared to the positions of particles in an equal volume of liquid can be described as follows:
- In a solid, the particles are tightly packed and held in a fixed position, vibrating around a fixed point. The attractive forces between the particles are strong, keeping them in a regular pattern.
- In a liquid, the particles are still close together but are free to move and slide past one another. The attractive forces between the particles are weaker compared to solids, allowing the particles to flow and take the shape of their container.
