The complete question is given below:
Two students are given different samples of a substance and are instructed to determine the properties of the substance.
Which statement describes a property that will be the same for both students?
A. color because it is an extensive property
B. mass because it is an extensive property
C. boiling point because it is an intensive property
D. volume because it is an intensive property .
ANSWER
The correct option is C.
The physical properties of substances are divided into two, intensive and extensive properties.
Intensive properties refers to those features of a substance that do not depend on the quantity of the material that is available. Whether the sample available is big or small, the intensive properties remain the same. Examples of intensive properties are: melting point, boiling point, refractive index, hardness, density color, etc. This question is asking us to look for an intensive property.
Extensive properties refers to those characteristics of a substance that depend on the amount of substance present. Examples of these properties are: mass, volume, size, weight, length, etc.
From the options given, option A is wrong because color is not an extensive property, it is intensive. Option B is wrong because the mass depend on the amount of sample given and the same thing apply to option D.
The correct option is C, because no matter the quantity of that substance that you have, the boiling point will always remains the same.
