Which of the following is an extensive property?
a) Boiling point
b) Magnetism
c) Melting point
d) Volum
d) Volume
An extensive property is a property that depends on the amount or size of a sample.
Out of the options provided, the extensive property is:
d) Volume
Volume is a property that depends on the amount of substance present. As the amount or size of the sample increases, the volume of the substance also increases.
To determine which of the given options is an extensive property, we need to first understand what extensive properties are.
Extensive properties are the properties that depend on the amount or size of a substance. These properties change when the amount of substance changes.
Now, let's go through each option and analyze whether it is an extensive property:
a) Boiling point: The boiling point of a substance is the temperature at which it changes from its liquid phase to its gaseous phase. The boiling point does not depend on the amount of the substance; it only depends on the type of substance. Therefore, boiling point is not an extensive property.
b) Magnetism: Magnetism is not an extensive property either. It is a characteristic of certain materials or objects and does not change with the amount or size of the material.
c) Melting point: Similar to the boiling point, the melting point is the temperature at which a substance changes from its solid phase to its liquid phase. Like the boiling point, the melting point is also a characteristic of a substance and does not depend on the amount of the substance. Therefore, melting point is not an extensive property.
d) Volume: The volume of a substance is the amount of space it occupies. Volume is an example of an extensive property because it directly depends on the amount or size of the substance. If you increase the amount of substance, the volume will also increase.
Therefore, the answer is:
d) Volum
