Chapter 1, Problem 1.20P

(a)

Interpretation Introduction

Interpretation:

Whether the density increases, decreases or remains the same when a sample of chlorine gas is compressed is to be determined.

Concept introduction:

The density of the substance is defined as the mass per unit volume. It is represented by $\rho$ and its unit is ${\text{kg/m}}^3$.

The formula to calculate the density of the substance is as follows:

$\text{Density of substance}\left(\rho \right)=\frac{\text{Mass of substance}\left(M\right)}{\text{Volume of substance}\left(V\right)}$        (1)

(b)

Interpretation Introduction

Interpretation:

Whether the density increases, decreases or remains the same when a lead weight is carried up a high mountain is to be determined.

Concept introduction:

The density of the substance is defined as the mass per unit volume. It is represented by $\rho$ and its unit is ${\text{kg/m}}^3$.

The formula to calculate the density of the substance is as follows:

$\text{Density of substance}\left(\rho \right)=\frac{\text{Mass of substance}\left(M\right)}{\text{Volume of substance}\left(V\right)}$        (1)

(c)

Interpretation Introduction

Interpretation:

Whether the density increases, decreases or remains the same when a sample of water is frozen is to be determined.

Concept introduction:

The density of the substance is defined as the mass per unit volume. It is represented by $\rho$ and its unit is ${\text{kg/m}}^3$.

The formula to calculate the density of the substance is as follows:

$\text{Density of substance}\left(\rho \right)=\frac{\text{Mass of substance}\left(M\right)}{\text{Volume of substance}\left(V\right)}$        (1)

(d)

Interpretation Introduction

Interpretation:

Whether the density increases, decreases or remains the same when an iron bar is cooled is to be determined.

Concept introduction:

The density of the substance is defined as the mass per unit volume. It is represented by $\rho$ and its unit is ${\text{kg/m}}^3$.

The formula to calculate the density of the substance is as follows:

$\text{Density of substance}\left(\rho \right)=\frac{\text{Mass of substance}\left(M\right)}{\text{Volume of substance}\left(V\right)}$        (1)

(e)

Interpretation Introduction

Interpretation:

Whether the density increases, decreases or remains the same when a diamond is submerged in water is to be determined.

Concept introduction:

The density of the substance is defined as the mass per unit volume. It is represented by $\rho$ and its unit is ${\text{kg/m}}^3$.

The formula to calculate the density of the substance is as follows:

$\text{Density of substance}\left(\rho \right)=\frac{\text{Mass of substance}\left(M\right)}{\text{Volume of substance}\left(V\right)}$        (1)
