does lego bricks is an example of solids?

tell me one of the postulates of the particle theory (no 1-5 according to the presentation in gclass) (make sure to use capital letters and full stops)

• All matter is made up of tiny particles known as atoms.

• Particles of matter are constantly in motion.

• Particles of matter attract each other.

• Particles of matter have spaces between them.

• As temperature increases, particles of matter move faster.

what is the brownian motion?

• the movement of particles to create a solid
• the random motion of particles suspended in a medium gas or liquid. This motion make substances' stable
• the elimination of particles by using an atom destroyer
• the nuclear radiation produced by radioactive materials
