January 17, 2014
Research Question- How does solvent temperature affect diffusion rate through a membrane?
Background InformationOsmosis is the diffusion of molecules across
Evaluation & Conclusion
In conclusion, the hypothesis was correct on both counts. The closer the height was to
the diameter, and the thicker the material, the more mass the column held. The columns that
were 5.5 inches high, the height closest to the diam
Design - Variables
