The particulate theory of Matter

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.

Dust Particles seen dancing in a beam of light is an example of_____________.

• Diffusion

• Brownian's motion

• Osmosis
