Engineers are investigating the properties of a material for use as a wrapping product. Three identical
sheets of the material are placed in different temperature water baths. A 20 g weight is attached to the
bottom of each sheet and the amount each sheet stretches is measured. The results are in the table.
Temperature (°C) Distance stretched (mm)
