Casey is comparing different substances by measuring their weights and volumes. He measures the volume displacement of a 15 g br
ass rod to be 10.0 mL. He measures the volume displacement of 15 g of packing peanuts to be 34.5 mL. Why is there so much difference in the displacement? A) The heavier brass rod takes up so much more volume for the given mass.
B) The masses are incorrect. They could not weigh the same if the volumes differ.
C) The packing peanuts weigh very little individually and so they take up more volume for a given mass.
D) The measurements are incorrect. The masses are the same and the volumes should be as well.
