Chapter 3, Problem 108A

Interpretation Introduction

Interpretation : The arrangement of the layers of liquids in the beaker is to be described.

Concept Introduction : The measure of how densely a material is packed together is called density. It is described as the mass per unit volume.

Answer to Problem 108A

The arrangement of the layers of liquid in the beaker is corn oil on the top, water in the middle, and mercury on the bottom.

Explanation of Solution

Density is defined as the ratio of mass to volume. It gives the connectivity between mass and volume.

The formula of density is given as:

  $\text{Density =}\frac{\text{mass}}{\text{volume}}$

To describe the layers of liquids, the density value of the liquid is to be compared.

The density of mercury is $13.6{\text{g/cm}}^3$ .

The density of water is $1.00{\text{g/cm}}^3$ .

The density of corn oil is $0.922{\text{g/cm}}^3$ .

Among the values of densities, mercury has a higher density so it will be the densest liquid and stays at the bottom.

Corn oil is less dense than water so it will be in the upper layer while water will be in the middle layer.

Corn oil, water, and mercury is the layers of liquid in the beaker.

The density of neon and hydrogen is smaller than the density of the air, so these balloons rise up. Among these balloons, the hydrogen-filled balloon goes up at a faster rate due to low density.

The density of carbon dioxide is higher than the density of the air, so the balloon sinks.

Interpretation Introduction

Interpretation : The location of the small sugar cube to be described.

Concept Introduction : The measure of how densely a material is packed together is called density. It is described as the mass per unit volume.

Answer to Problem 108A

The small sugar cube will be placed in between water and mercury.

Explanation of Solution

Density is defined as the ratio of mass to volume. It gives the connectivity between mass and volume.

The formula of density is given as:

  $\text{Density =}\frac{\text{mass}}{\text{volume}}$

Sugar is denser than water but soluble in water.

When sugar cubes are put into the water, it settles down in the water.

The location of sugar will be in between water and mercury.

Interpretation Introduction

Interpretation : The change that occurs to the sugar cube over time is to be described.

Concept Introduction : The measure of how densely a material is packed together is called density. It is described as the mass per unit volume.

Answer to Problem 108A

The sugar won’t be visible if it gets dissolved in water.

Explanation of Solution

Density is defined as the ratio of mass to volume. It gives the connectivity between mass and volume.

The formula of density is given as:

  $\text{Density =}\frac{\text{mass}}{\text{volume}}$

Sugar is denser than water but soluble in water.

When sugar cubes are put into the water, it settles down in the water.

The location of sugar will be in between water and mercury.

Over time, sugar gets dissolved in water.
