A student investigated transpirational water loss in two different plant species, Plant P and Plant Q, over a 4-hour period. The results are shown in the graph below.

A line graph with the horizontal axis labeled 'Time in hours' ranging from 0 to 4 with major increments at 1 hour. The vertical axis is labeled 'Volume of water lost in cm³' and ranges from 0 to 30. Two lines represent Plant P and Plant Q starting at (0,0). The line for Plant P connects the points (0, 0), (2, 12), and (4, 28). The line for Plant Q connects the points (0, 0), (2, 4), and (4, 14).

a.

Calculate the difference in the volume of water lost by Plant P compared to Plant Q at 2 hours. Show your working.

b.

Calculate the average rate of water loss for Plant P between 2 hours and 4 hours. Include the correct unit in your answer.
