Question

differentiating intensive and extensive properties
the pictures to the right show two samples of substance x. answer the questions below about the intensive and extensive properties of substance x. you may assume that both cubes are solid (that is, not hollow inside).
sample a melts at
sample b.
sample b has
sample a.
sample a has
sample b.
if sample a floats in water, sample b
if sample b is attracted to a magnet, sample a

Explanation:

Intensive properties do not depend on the amount of substance (like melting - point, density, magnetic properties). Extensive properties depend on the amount of substance (like mass, volume). Melting - point is an intensive property, so Sample A and Sample B have the same melting - point. Mass and volume are extensive properties, so Sample B has more mass and volume than Sample A. Floating ability depends on density (intensive), so if Sample A floats, Sample B also floats. Magnetic attraction is an intensive property, so if Sample B is attracted to a magnet, Sample A is also attracted.

Answer:

Sample A melts at the same temperature as sample B.
Sample B has more mass/volume than sample A.
Sample A has less mass/volume than sample B.
If sample A floats in water, sample B also floats.
If sample B is attracted to a magnet, sample A is also attracted.
