What is the correct definition of diffusion?
The movement of particles from an area of high concentration to an area of low concentration
The movement of particles from an area of low concentration to an area of high concentration
Movement from high concentration to low concentration
Movement of gases
What factor will effect the rate of diffusion more in the human body?
the temperature
The concentration Gradient
The type of gas
The area of the body
Where is an example of where diffusion happens?
Carbon Dioxide from the lungs to the blood in the body
Oxygen from the lungs to the blood in the body
The uptake of water in the roots
Why does diffusion not happen in solids?
The bonds between the particles are too strong
They are too hard
There is no concentration gradient
The particles cannot move
