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
