Classify as an intensive property of matter
-
Density
-
Boiling Point
-
Color
-
The mass of a substance
Correct Answer(s)
A. Density
A. Boiling Point
A. The mass of a substanceExplanation
The given options can be classified as intensive properties of matter because they do not depend on the amount or size of the substance. Density is the mass per unit volume, which remains constant regardless of the amount of the substance. Boiling point is the temperature at which a substance changes from a liquid to a gas, and it is a characteristic property of the substance. The mass of a substance is also an intensive property as it remains the same regardless of the amount of the substance.Rate this question:

-
Your T shirt size
Correct Answer(s)
A. The volume of a Mug
A. Your T shirt sizeExplanation
The volume of a mug and your T-shirt size are examples of extensive properties of matter. Extensive properties are dependent on the amount or size of the substance being considered. In this case, the volume of a mug will vary depending on the size of the mug, and your T-shirt size will vary depending on your body size. These properties cannot be determined without considering the specific quantity or size of the matter being measured. On the other hand, density and the number of calories when consuming sugar are examples of intensive properties, which do not depend on the amount or size of the substance.Rate this question:
