Concept explainers
(a)
Interpretation: Whether the density of a sample of chlorine gas increases, decreases, or remains the same needs to be determined if it is compressed.
Concept Introduction: Density is related to mass and volume as follows:
Here, m is mass and V is volume.
The density of a substance mainly depends on two factors, that is mass and volume. From the formula, it can be said that density is directly proportional to mass and inversely proportional to volume.
Thus, if the mass increases, density increases, and if volume increases, density decreases.
(b)
Interpretation: Whether the density of the lead weight increases, decreases, or remains the same needs to be determined if it is carried up a high mountain.
Concept Introduction: Density is related to mass and volume as follows:
Here, m is mass and V is volume.
The density of a substance mainly depends on two factors that is mass and volume. From the formula, it can be said that density is directly proportional to mass and inversely proportional to volume.
Thus, if the mass increases, density increases, and if volume increases, density decreases.
(c)
Interpretation: Whether the density of the sample of water increases, decreases, or remains the same needs to be determined if it is frozen.
Concept Introduction: Density is related to mass and volume as follows:
Here, m is mass and V is volume.
The density of a substance mainly depends on two factors that is mass and volume. From the formula, it can be said that density is directly proportional to mass and inversely proportional to volume.
Thus, if the mass increases, density increases, and if volume increases, density decreases.
(d)
Interpretation: Whether the density of an iron bar increases, decreases, or remains the same needs to be determined if it is cooled.
Concept Introduction: Density is related to mass and volume as follows:
Here, m is mass and V is volume.
The density of a substance mainly depends on two factors that is mass and volume. From the formula, it can be said that density is directly proportional to mass and inversely proportional to volume.
Thus, if the mass increases, density increases, and if volume increases, density decreases.
(d)
Interpretation: Whether the density of a diamond increases, decreases, or remains the same needs to be determined if it is submerged in water.
Concept Introduction: Density is related to mass and volume as follows:
Here, m is mass and V is volume.
The density of a substance mainly depends on two factors, that is mass and volume. From the formula, it can be said that density is directly proportional to mass and inversely proportional to volume.
Thus, if the mass increases, density increases, and if volume increases, density decreases.
