How Brownian Motion Helped Prove the Existence of Atoms

What is the significance of the random motion observed around the closterium?

• It shows the coordinated movement of organisms.

• It serves as evidence for the existence of atoms.

• It is a metaphor for life's unpredictability.

• It indicates the presence of microbes.

Who proposed the idea of 'atomos' and what did it mean?

• John Dalton, meaning atomic

• Plato, meaning elemental

• Democritus, meaning uncuttable

• Aristotle, meaning indivisible

What was Robert Brown originally studying when he discovered Brownian motion?

• The structure of atoms

• The behavior of gases

• The motion of pollen grains

• The properties of water molecules

What did Robert Brown conclude about the motion he observed in pollen grains?

• It was unique to living organisms.

• It was due to the kinetic energy of atoms.

• It was a biological phenomenon.

• It was caused by air currents.

How did Einstein contribute to the understanding of Brownian motion?

• He used it to disprove atomic theory.

• He provided a theoretical framework explaining it.

• He discovered it while studying gases.

• He observed it in living organisms.

What was the role of Jean Pellas in the study of Brownian motion?

• He confirmed Einstein's equations experimentally.

• He disproved Einstein's theories.

• He discovered Brownian motion.

• He proposed the theory of gases.

What does Brownian motion demonstrate about the nature of atoms?

• Atoms are only theoretical constructs.

• Atoms are constantly in motion due to kinetic energy.

• Atoms are stationary and inert.

• Atoms are large and visible.
