Hopefully you have now sketched graphs for some of the nine processes described in the previous section. What features did you consider as you did this?
Below is a possible graph for each process (but they’re muddled up). Can you match a graph to each process?
How do the graphs below compare to those you sketched? If you sketched something different, can you identify the assumptions that you made and those that might have led to the graphs below?

Hopefully you have now matched a graph to each process.
Can you suggest an equation for each process/graph pair?
