During my investigation I will not actually be able to measure a value for, as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a …showed first 75 words of 2007 total…
