SB8b: 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 µ

Surface area x concentration difference
———————————————————
Thickness of membrane

Question 5

Inversely proportional

Answer 5

A relationship 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.
