Final answer:
The three states of matter can be arranged in order of increasing kinetic energy of their particles as solid, liquid, and gas. On the other hand, the order of decreasing densities can be arranged as solid, liquid, and gas.
Step-by-step explanation:
The three states of matter can be arranged in order of increasing kinetic energy of their particles as follows:
Solid: Particles have the lowest kinetic energy as they vibrate in fixed positions.
Liquid: Particles have higher kinetic energy compared to solids as they can move around and slide past one another.
Gas: Particles have the highest kinetic energy as they move freely and independently.
In terms of density, the three states of matter can be arranged in order of decreasing density as follows:
Solid: Generally has the highest density as particles are tightly packed together.
Liquid: Generally has a lower density than solids as particles are more spread out.
Gas: Generally has the lowest density as particles are far apart and have more space between them.
