SP8b Factors Affecting Diffusion

Question 1

concentration

Answer 1

the amount of solute dissolved in a certain amount of solution

Question 2

concentration gradient

Answer 2

the difference between two concentrations - there will be an overall movement of particles down a concentration gradient, from higher concentration to lower concentration

Question 3

directly proportional

Answer 3

a relationship between two variables in which if one variable doubles, the other also doubles

Question 4

Fick’s law

Answer 4

the relationship between the different variables that affect diffusion

rate of diffusion is directly proportional to:

(surface area * conc difference) / thickness of membrane

Question 5

inversely proportional

Answer 5

a relation ship between two variables in which if one variable doubles, the other halves

Question 6

linear relationship

Answer 6

a relationship between two variables shown by a straight line on a graph
