Concept explainers
Interpretation:
Whether melting point is an intensive property or extensive property needs to be explained.
Concept introduction:
The physical change is a change temporarily change. Itis a reversible change. Physical properties are the physical appearance of any substance. Physical properties are constant for each substance. These properties are classified as extensive properties or intensive properties.
Answer to Problem 34A
The Melting point is an intensive property.
Explanation of Solution
The property that does not affect by the quantity of the substance and only depends on nature is known as intensive properties. For example, temperature, boiling point, density, etc.
The property that depends on the amount of the substance is known as extensive properties. For example, mass, volume, weight, etc.
When the solid is transfer into the liquid state at a particular temperature, that temperature is known as melting point. The melting point of a substance is the change in the phase.
Melting point is a fixed value for any type of substance. That means it independent on the amount of substance. So, the melting point is an intensive property.
(b)
Interpretation:
Whether mass is an intensive property or extensive property needs to be determined.
Concept introduction:
The physical change is a change temporarily change. Itis a reversible change. Physical properties are the physical appearance of any substance. Physical properties are constant for each substance. These properties are classified as extensive properties or intensive properties.

Answer to Problem 34A
The mass is an extensive property.
Explanation of Solution
The property that does not affect by the quantity of the substance and only depends on nature is known as intensive properties. For example, temperature, boiling point, density, etc.
The property that depends on the amount of the substance is known as extensive properties. For example, mass, volume, weight, etc.
Mass is directly depending upon the size of object. Mass of any substance will be increase when the amount of substance increases. It concluded that it is affected by the quantity of the substances. So, mass is an extensive property.
(c)
Interpretation:
Whether density is an intensive property or extensive property needs to be explained.
Concept introduction:
The physical change is a change temporarily change. Itis a reversible change. Physical properties are the physical appearance of any substance. Physical properties are constant for each substance. These properties are classified as extensive properties or intensive properties.

Answer to Problem 34A
Density is an intensive property.
Explanation of Solution
The property that does not affect by the quantity of the substance and only depends on nature is known as intensive properties. For example, temperature, boiling point, density, etc.
The property that depends on the amount of the substance is known as extensive properties. For example, mass, volume, weight, etc.
If the amount of substance increases or decreases, the density remains the same for substance. The density is the ratio of two extensive properties, mass, and volume. Density is fixed for any substance. So, it is an intensive property.
(d)
Interpretation:
Whether length is an intensive or extensive property needs to be explained.
Concept introduction:
The physical change is a change temporarily change. Itis a reversible change. Physical properties are the physical appearance of any substance. Physical properties are constant for each substance. These properties are classified as extensive properties or intensive properties.
(d)
Answer to Problem 34A
The length of any object is an extensive property.
Explanation of Solution
The property that does not affect by the quantity of the substance and only depends on nature is known as intensive properties. For example, temperature, boiling point, density, etc.
The property that depends on the amount of the substance is known as extensive properties. For example, mass, volume, weight, etc.
The extensive property depends on the quantity of the object. The length is directly propositional to the size of the object. As the size of an objectincreases, the length will be increase accordingly. So, length of any object is an extensive property
