Aim
|
To correlate different sizes of cubes with total surface area/volume
(TSA/V) ratio.
|
|
Hypothesis
|
The smaller
the size of cube, the larger the
TSA/V ratio; the higher the percentage of coloured area.
|
|
Variables
|
MV : Size of cubes
RV : The percentage of coloured area
FV : Temperature,
time taken, type of potato

1.
A big object has a low TSA/V ratio in which the
movement of solutes through diffusion is less.
