Question

How do particles move in different states of matter?

Answer 1

We know that there are three states of matter- solid, liquid and gas. Particles in the gas phase are well separated with no regular arrangement. In the liquid phase, the particles are close together with no regular arrangement. In solid, the particles are tightly packed usually in a regular pattern.

Complete answer:
The particles in a gas phase move quickly and are able to spread apart from one another. They do vibrate and move freely at high speeds. The force of attraction between them is very weak. The particles possess a higher average kinetic energy than the particles in other phases and hence these particles move the fastest.
The particles in a liquid phase are able to move past each other. They vibrate, move about and slide past each other.
The particles of a solid are not able to move out of their positions relative to one another but they do have small vibrational movements. They do vibrate(jiggle) but generally do not move from place to place. The force of attraction between them is very strong.

Additional information: Liquids and gases are often referred to as condensed phases because the particles are very close together. In extreme environments, other states such as plasma, Bose-Einstein condensates and neutron stars may be present.

Note: In gases, the particles can move past one another. In liquids, the particles can move/slide past one another. In solids, particles are rigid and hence cannot move/slide past one another.
