An object with a density of 0.75 g/cm³ is dropped into each of the two beakers shown below. What will happen to the object in each case?

• It will sink in both beakers

• It will float in beaker 1 and sink in beaker 2.

• It will sink in beaker 1 and float in beaker 2

• It will float in both beakers

An object with unknown density is tested in two beakers. Beaker 1 contains liquid with a density of 1.5 g/mL, and Beaker 2 contains liquid with a density of 2.0 g/mL. The object sinks in both beakers. Which of the following statements about the object's density is true?

• The object's density is less than 1.5 g/cm³

• The object's density is exactly 1.5 g/cm³

• The object's density is greater than 1.5 g/cm³ and less than 2.0 g/cm³

• The object's density is greater than 2.0 g/cm³
