The phases of matter can be ranked based on the kinetic energy of their particles, from least to greatest kinetic energy, as follows:
- Solid - Particles are closely packed and vibrate in place, resulting in the lowest kinetic energy.
- Liquid - Particles are still close together but can move past one another, leading to higher kinetic energy than solids.
- Gas - Particles are far apart and move freely, resulting in the highest kinetic energy among the common phases of matter.
In summary: Solid < Liquid < Gas.
