Diffusion

Question 1

What is Diffusion

Answer 1

Diffusion is the net movement of particles from an area of high concentration to an area of low concentration

Question 2

What states does diffusion normally happen in

Answer 2

Gases
In solutions (Aqueous)

Question 3

What are three factors that affect the rate of diffusion?

Answer 3

Cocncentraion Gradient
Temperature
Surface area

Question 4

Concentration Gradient:

Answer 4

The higher the concentration gradient, The greater diffusion will be.
This is because the net movement on one side is greater than the other.

Question 5

Temperature:

Answer 5

The higher the temperature the greater the rate of diffusion because the particles gain more energy which allows them to move fast

Question 6

Surface area:

Answer 6

The greater the surface are, the greater the rate of diffusion
this is because more particles will able to move at the same time.

Question 7

Does it require a lot of energy?

Answer 7

No
