13 Kate placed 100 mL of water in five

different pans, placed the pans on a

windowsill for a week, and measured

how much water evaporated from each

pan. Draw a graph of her data, which

is shown below. Place surface area on

the x-axis and volume evaporated on

the y-axis. Is the graph linear or non-

linear? What does this information

tell you?
