Read each question carefully and answer to the best of your ability. Good luck!
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. This process happens naturally and doesn't require any energy.
1. What is diffusion?
Movement of particles from low to high concentration
Movement of particles from high to low concentration
Movement of water only
Movement that requires energy
2. Which of the following is an example of diffusion?
A ball rolling down a hill
Sugar dissolving in water
The smell of perfume spreading through a room
Water freezing into ice
3. Diffusion occurs when particles move from an area of high to an area of low .
4. The process of diffusion does not require any from the cell or system.
5. Diffusion only happens in gases.
True
False
6. Heating a substance can make diffusion happen faster.
True
False
7. Imagine you spray air freshener in one corner of a room. Explain how the smell eventually reaches the other side of the room using the concept of diffusion.
This image shows molecules moving in a simple diffusion process.
8. Based on the image and your understanding of diffusion, describe what is happening to the molecules over time.
