Diffustion Flashcards
1
Q
What is diffusion ?
A
The movement of particles from a high concentration to a low concentration
2
Q
What are the 3 factors that affect diffusion?
A
Temperature , surface area , concentration gradient
3
Q
Explain how increasing the temperature affects the rate of diffusion?
A
The particles gain more kinetic energy high increases the rate of diffusion
4
Q
How will the surface area affect the rate of diffusion?
A
The larger the surface area , the faster the rate of diffusion. This is because there is more surface membrane fir the molecules to diffuse through.
5
Q
How will the concentration gradient affect the rate of diffusion?
A
The greater the difference in concentration, the quicker the rate of diffusion.
