Brownian Motion & Gas Pressure

What is an example of Brownian motion?

• The movement of water molecules in a beaker

• The movement of air molecules

• The movement of solid molecules

• The movement of smoke particles in air

Pollen grains suspended in water exhibit Brownian motion. How do they move?

• In smooth curves

• Randomly

• Orderly with a pattern

• In straight lines with no change of direction

3. Identify the states of matter where Brownian Motion can occur.

• a) Solid, liquid, gas
• b) Liquid, gas
• c) Solid, gas
• d) Solid, liquid

The speed of the molecules determines the _____.

• density

• size

• matter

• temperature

Which container will have lower pressure?

• left
• right
• they both have the same pressure

Pressure in gases is a measure of:

• the number of collisions per second of the particles with the side of the container.

• The size of the particles inside a container.

• the amount of space taken up by the particles in the container.

• How much stress they can take before having a stroke.

The pressure inside the balloon will:

• Decrease

• Increase

• Remain the same

• Not enough information to formulate an answer
