						CHAPTER 1 –   TRANSPORT  ( TSA / V )
Aim/ Objective : To study the relationship between total surface area per volume ratio and the rate of diffusion. √ E1 PI 1 Problem  : What is the relationship between total surface area per volume ratio and the rate of diffusion? √ E1 PI 2 Hypothesis  :  The larger the total surface area per volume ratio / the smaller the size of cube, the faster the rate of diffusion. √ E1 PI 3  Variables    Manipulated  :  Total surface area per volume ratio / the size of cubes. Responding  :  Rate of diffusion. √ E1 PI 4  Fixed  :  Colored water temperature / time taken.  Material  :  Potato, Colored water. Apparatus  :  Penknife, white tiles, beaker, forceps, basin and gridded transparency. √ E1 PI 5 Technique  :  Calculate the rate of diffusion by using a formula. Rate of diffusion = Percentage of colored area  (%min-1)                   Time taken  √ E1 PI 6  Procedure  :  √ E1 PI 7
