The phases of matter ranked from least kinetic energy to greatest kinetic energy for the particles in the substance are as follows:
- Solid
- Liquid
- Gas
So the correct order is:
Solid < Liquid < Gas
In solids, particles have the least kinetic energy and are closely packed together. In liquids, particles have more kinetic energy and can move past each other freely, while in gases, particles have the greatest kinetic energy and move very far apart and independently.
