Understanding Brownian Motion

What is Brownian motion?

• The random movement of particles in a fluid due to their collisions with other particles.

• The uniform movement of particles in a straight line.

• The movement of particles in a circular path.

• The movement of particles due to gravitational forces.

Who first observed Brownian motion?

• Isaac Newton

• Albert Einstein

• Robert Brown

• James Clerk Maxwell

How does Brownian motion relate to kinetic theory?

• It demonstrates that particles are stationary.

• It shows that particles move in a predictable pattern.

• It provides evidence that particles are in constant, random motion.

• It proves that particles do not interact with each other.

Which of the following best describes the visualisation of Brownian motion?

• Particles moving in straight lines.

• Particles moving in a zigzag pattern.

• Particles moving in a circular path.

• Particles remaining stationary.

In which type of medium is Brownian motion most commonly observed?

• Solid

• Liquid

• Gas

• Plasma

What is the primary cause of Brownian motion?

• Gravitational forces

• Magnetic forces

• Collisions with other particles

• Electrical forces

Which scientist provided a theoretical explanation for Brownian motion?

• Isaac Newton

• Albert Einstein

• Robert Brown

• James Clerk Maxwell

What is the significance of Brownian motion in the context of kinetic theory?

• It disproves the kinetic theory.

• It supports the idea that particles are in constant motion.

• It shows that particles are stationary.

• It indicates that particles move in a uniform direction.

Which of the following is an example of Brownian motion?

• A car moving on a road.

• Dust particles moving randomly in a beam of light.

• A ball rolling down a hill.

• A bird flying in the sky.

How can Brownian motion be observed in a laboratory setting?

• By observing the movement of pollen grains in water under a microscope.

• By observing the movement of a pendulum.

• By observing the movement of a car on a road.

• By observing the movement of a ball in a field.
