A student measures the density of two different samples of aluminum. What should the student expect about the density of these samples?

• The density will be different for each sample.

• The density will be the same for both samples.

• The density will depend on the shape of the samples.

• The density will depend on the color of the samples.

If a substance has a melting point of 100°C, what can be inferred about its boiling point?

• It must be less than 100°C.

• It must be exactly 100°C.

• It must be greater than 100°C.

• It cannot be determined from the melting point.
