Factors affecting the rate of osmosis plan aim to find out if osmosis occurs in a potato, and to observe how different concentrations of a solution affect the rate of osmosis in.
Yes the rate of osmosis is determined by several factors, including heat, molecule size, and concentration gradient the concentration gradient is essentially the difference between the concentration within part of the system to that concentration in the rest of the system. The purpose of this experiment was to test different solute concentrations on the rate of osmosis artificial cells were filled with different solute concentrations and placed in water and weighed at equal time intervals to show how the water moves across cell membranes and down its concentration gradient into the lower concentrated area.
