The correct order of states of matter in terms of increasing empty space between particles, starting with the state where particles are closest together, is:
- Solid - Particles are closely packed together in a fixed arrangement.
- Liquid - Particles are still close but can move past one another, allowing for more empty space than in solids.
- Gas - Particles are far apart and move freely, resulting in a large amount of empty space between them.
- Plasma - Similar to gas, but with charged particles and even more energy, resulting in even greater distances between particles.
So the order from closest to furthest apart is: Solid → Liquid → Gas → Plasma.
