A scientist has 1.00 kilogram of pure
calcium carbonate solid. She
measures a property of the calcium
carbonate, and finds that
1.00 kilogram measures z units. She
then separates a 10-gram sample
from the calcium carbonate and
measures property Z of the smaller
sample. She finds that the smaller
sample also measures z units. Which
of the following best describes
property Z?
A Z is an extensive property
because it does not vary with the
size of the sample.
B Z is an intensive property because
z is positive for all sample sizes.
CZ is an intensive property because
it does not vary with the size of
the sample.
D Z is an extensive property
because z is positive for all
sample sizes.

The property Z, (C) is an intensive property because it does not vary with the size of the sample.

For matter, we can recognize 2 kinds of physical properties:

  • Intensive properties: do not depend on the system size or the amount of material in the system (e.g. density, temperature)
  • Extensive properties: depend on the system size or the amount of material in the system (mass, volume)

In this case, property Z does not vary whether it is measured in a 1.00 kg-sample or in a 10-gram sample.

Which of the following best describes property Z?

A) Z is an extensive property because it does not vary with the size of the sample. NO. This is the definition of an intensive property.

B) Z is an intensive property because z is positive for all sample sizes. NO. This is not part of the definition of intensive properties.

C) Z is an intensive property because it does not vary with the size of the sample. YES. This is the definition of an intensive property.

D) Z is an extensive property because z is positive for all sample sizes. NO. This is not part of the definition of extensive properties.

The property Z, (C) is an intensive property because it does not vary with the size of the sample.
