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.
