Answer:
Step-by-step explanation:
The relative speed and distance of atoms in a substance depend on the state of matter.
In a solid, atoms are closely packed together and have minimal movement or vibration. Their relative speed is low and their distance from one another is short.
In a liquid, atoms are still close together but have more movement and freedom of movement than in a solid. Their relative speed is slightly higher than in a solid, and their distance from one another is slightly longer.
In a gas, atoms are widely spaced and have a high degree of movement and freedom of movement. Their relative speed is much higher than in a solid or liquid, and their distance from one another is much greater.
In a plasma, atoms are ionized and have a high degree of movement and freedom of movement. Their relative speed is much higher than in a solid, liquid or gas, and their distance from one another is much greater.
