Understanding Diffusion

What is the primary driving force behind the process of diffusion?

• Temperature

• Pressure

• Gravity

• Concentration gradient

In the trash can example, what happens to the stink molecules when the lid is opened?

• They remain inside the can

• They move to an area of higher concentration

• They disperse to an area of lower concentration

• They evaporate

What does the green circle represent in the trash can example?

• Air molecules

• Sugar molecules

• Stink molecules

• Water molecules

In the lemonade example, which side of the glass would taste sweeter initially?

• Side A

• Side B

• Neither side is sweet

• Both sides taste the same

What is the result of diffusion in the lemonade example after the barrier is removed?

• No change in distribution

• Increased concentration on one side

• Unequal distribution of particles

• Equal distribution of particles
