Objects 1 and 2 float as shown in the beaker below. The density of the liquid in the beaker is 3.2 g/mL. Which of the densities given below are possible values for the densities of the two objects?
- Density of object 1 = 4.4 g/cm3 Density of object 2 = 4.0 g/cm3
- Density of object 1 = 3.0 g/cm3 Density of object 2 = 1.8 g/cm3
- Density of object 1 = 1.6 g/cm3 Density of object 2 = 2.9 g/cm3
- Density of object 1 = 2.5 g/cm3 Density of object 2 = 3.8 g/cm3
Correct Answer

A. Density of object 1 = 3.0 g/cm3 Density of object 2 = 1.8 g/cm3

Explanation

The density of an object determines whether it will float or sink in a liquid. If the density of an object is less than the density of the liquid, it will float. In this case, the density of object 1 is 3.0 g/cm3, which is less than the density of the liquid (3.2 g/mL), so object 1 will float. Similarly, the density of object 2 is 1.8 g/cm3, which is also less than the density of the liquid, so object 2 will float as well. Therefore, the given densities of object 1 and object 2 are possible values for their densities.

Identical objects are placed in Beaker A and in Beaker B. The objects float as shown in the diagrams below. What can you conclude about the liquid in each of the beakers?
- Both liquids are less dense than the object.
- The liquid in Beaker A has a greater density than the objects. The liquid in Beaker B is less dense than the objects.
- The liquid in Beaker A has a greater density than the liquid in Beaker B.
- The liquid in Beaker B has a greater density than the liquid in Beaker A.
Correct Answer

A. The liquid in Beaker B has a greater density than the liquid in Beaker A.

Explanation

The correct answer is that the liquid in Beaker B has a greater density than the liquid in Beaker A. This can be concluded because the objects are floating in Beaker A, indicating that the liquid in Beaker A is less dense than the objects. Since the objects are sinking in Beaker B, it can be inferred that the liquid in Beaker B is denser than the objects and therefore denser than the liquid in Beaker A.

Objects 1 and 2 are placed in the beaker below. The density of the liquid in the beaker is 2.0 g/mL. Which of the densities given below are possible values for the densities of the two objects?
- Density of object 1 = 0.8 g/cm3 Density of object 2 = 3.0 g/cm3
- Density of object 1 = 3.0 g/cm3 Density of object 2 = 0.8 g/cm3
- Density of object 1 = 3.8 g/cm3 Density of object 2 = 3.0 g/cm3
- Density of object 1 = 1.5 g/cm3 Density of object 2 = 0.8 g/cm3
Correct Answer

A. Density of object 1 = 3.0 g/cm3 Density of object 2 = 0.8 g/cm3

Explanation

The density of an object is determined by its mass and volume. In this question, object 1 has a density of 3.0 g/cm3 and object 2 has a density of 0.8 g/cm3. Since the density of the liquid in the beaker is 2.0 g/mL, it is possible for object 1 to be denser than the liquid and for object 2 to be less dense than the liquid. Therefore, the given densities of object 1 and object 2 are possible values.

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.
Correct Answer

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

Explanation

Since the object sinks in both beakers, it must have a greater density than both liquids. The density of Beaker 1 is 1.5 g/mL and the density of Beaker 2 is 2.0 g/mL. Therefore, the object's density must be greater than 2.0 g/cm3.
