Physical Science Review

What property of matter can be used to classify the following objects into more than one group?

• magnetism

• electrical conductivity

• relative density

• state of matter

A team of science students tested properties of four different materials and recorded their results. Based on the data, which material would best insulate electrical wires?

• Material A

• Material B

• Material C

• Material D

A student needs to remove a metal spoon from a pan of boiling water. What should she do?

• Metal is a thermal insulator, so she should use protective gloves to remove the spoon.

• Metal is a thermal conductor, so she should use protective gloves to remove the spoon.

• Metal is a thermal insulator, so she should not use protective gloves to remove the spoon.

• Metal is a thermal conductor, so she should not use protective gloves to remove the spoon.

A team of science students observed properties of objects and recorded their observations in the table. What property of matter can be used to separate these objects into two different groups?

• magnetism

• relative density

• electrical conductivity

• solubility

• The fruits all float in water.

• The fruit are all solids.

• The fruits are all soluble in water.

• The fruits have equal mass.
