An evidence that proves that particles are in random motion is___________.
Diffusion
Osmosis
Surface Tension
Brownian's Motion
Which statement BEST summarizes that particulate theory of matter?
All matter are made of tiny particles that are in constant motion, have force of attraction between them, and occupies space.
All matter have tiny particles that are in constant motion when heat is applied, and will exhibit buoyancy when it occupies space.
All matter is has mass and occupies space hence matter change increases with kinetic energy.
All matter have particles, motion, force, and space.

Diffusion
Osmosis
Surface Tension
Brownian's Motion
