Diffusion: Post-Lab Questions 1.Record your hypothesis from Step 3 here. Be sure to support your hypothesis with evidence.
Homework Answers
Hypothesis:
The increase in the water temperature increases the rate of diffusion and if the water temerature get decreased rate of diffusion will decreased.
Evidence to support the hypothesis :
Potassium permagnate is added in different quantities in the water that show different rates of diffusion.
