... because the water particles have more energy and can move faster, so they will leave or enter the potato cells more quickly. At cold temperatures the water molecules will have less energy so less molecules will able to diffuse in the allotted time. If the temperature fluctuates significantly the results may be inaccurate, because osmosis will occur faster and 30 minutes at a cold temperature may give different results to 30 minutes at a warmer temperature. If time was extended this would not make a difference because equilibrium between the concentrations of the potato contents and the surrounding solution will still be reached. The temperature will therefore be regulated to room temperature. The size of the potato chip will affect the final mass, if I use a thin chip and a fat chip the average mass change per gram will be different because if they are placed in distilled water then ...
