Diffusion

Question 1

Diffusion is the?

Answer 1

Diffusion is the net movement of particles from a high concentration to a low concentration which does not require energy as it moves down the concentration gradient until it reaches dynamic equilibrium

Question 2

factors that affect diffusion is?

Answer 2

Concentration gradient ( high conc, higher r.o.d)
Temperature (higher temp, higher r.o.d due to inc kinetic energy)
Distance ( Shorter distance increases r.o.d)
Surface Area ( Larger SA:V ratio faster r.o.d)
Shape & sizes of molecules (Smaller molecules higher r.o.d)

Question 3

Increases surface area helps diffusion due to

Answer 3

larger s.a allows for more particles to diffuse at once.
