Matter is made up of particles: Proof
Matter is made up of tiny
particles is proved by the following process that occur in everyday life.
i.
Crystal growing
ii.
Diffusion
Crystal growing:
If a salt crystal is tied to an
end of a string and left in a saturated solution of its salt, untouched for a
few days; the particles of the salt from the solution will arrange themselves
on the salt crystal in the same ordered arrangement as the crystal itself, as
water evaporates from the solution, resulting in forming a single big crystal.
This is crystal growing. This suggest that matter is made up of particles.
