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

OBSERVE AND DETERMINE THE INCORRECT STATEMENT: 

• These are two beakers with liquids that have different densities.

• Beaker 2 is more dense than Beaker 1.

• Beaker 2 is possibly pure water.

• Beaker 1 is possibly pure water.

OBSERVE AND DETERMINE THE INCORRECT STATEMENT:

• Object 2 is less dense than Object 1 and the liquid in the beaker.

• Object 1 is less dense than Object 2.

• Object 1 and Object 2 are less dense than the liquid in the beaker.

• The liquid is more dense than the objects.

OBSERVE AND FIND THE INCORRECT (WRONG) STATEMENT:

• Object 2 has a density that is less than 2.0 g/mL

• Object 1 has a density that is greater than the liquid and Object 2.

• Object 1 has sunk because its density is greater than 2.0 g/mL

• The liquid in the beaker is more dense than both the objects.

TRUE or FALSE:

g/mL is the unit of measurement for DENSITY

• TRUE

• FALSE
