Your answer should be 100% original.

1. What might be reasons to explain the differences in the rate of diffusion?

2. Graph the two sets of results from Table 2 on the same graph using a computer spreadsheet program and include this graph in your report. Why is simultaneous graphing of the results useful here? What type of graph would best demonstrate rates of diffusion in gelatin versus liquid? Hint: The graph should show a continuity from To to T1 for both mediums.

3. What would be a graphic method to detect when the rate of diffusion in the gelatin was at maximum and was beginning to slow?

4. Construct a table that compares your results to the average of your classmates’ results, if available. Indicate how many classmates’ results are represented in the average (N=?). Include it in your report. Are results similar? If not, what might explain the differences in outcomes?
