This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again weighed to determine the amount of mass that they lost/gained and thus get an indication of the rate of osmosis. The results collected showed that the rate of osmosis was highest in the 70°C solution and lowest in the 20°C solution
