What can you tell about matter from how its particles move?

Answer 1

There are many ways that prove that the particles of matter are in continuous motion. The one I describe here is very simple to perform.

materials required: incense stick and a match box

procedure:

- put an unlit incense stick in a a corner of room

- now light up the incense stick.

observation: the smell of the unlit incense stick can be observed only by going close to it but the smell of lighted incense stick can be observed from a distance

conclusion:all the particles of matter posses kinetic energy{ability of particles to be in continuous motion} and kinetic energy increases with an increase in temperature.

Answer 2

The movement of particles in matter can give insight into its state. In solids, particles vibrate in fixed positions. In liquids, particles flow and slide past each other. In gases, particles move freely and rapidly.
