A balance and a graduated cylinder are used to determine the density of a mineral sample. The sample has a mass of 14.7 g and a volume 2.2 cm3. What is the density of the mineral sample?

• 0.15 g/cm3

• 32 g/cm3

• 13 g/cm3

• 6.7 g/cm3

A student is trying to classify an unidentified, solid gray material as a metal or nonmetal. Which question will best help the student classify the material?

• is the material malleable or ductile ?

• does the material feel hard to the touch?

• will the material float in water?

• does the material feel rough or smooth?

Aluminum, sulfur, and chlorine are elements found on the periodic table. Tests involving these three elements would show that at normal room temperature-

• sulfur is malleable and aluminum conducts electricity

• chlorine is malleable and conducts electricity

• aluminum is malleable and conducts electricity

• all three elements are malleable and conduct electricity

a bicycle rider is traveling up a hill. When the rider reaches the top of the hill, she stops to rest. Then she travels down the hill. The diagram shows the rider in the three different positions. Which of these correctly describes the potential energy and the kinetic energy of the bicycle rider?

• When the rider is at the top the hill, her potential energy is the greatest, and her kinetic energy is the least.

• as the rider moves up the hill, her kinetic energy increases, and her potential energy decreases.

• when the rider goes down the hill, her potential energy increases, and her kinetic energy decreases.

• as the rider reaches the bottom of the hill, her kinetic energy and her potential energy decreases.

Your science instructor gives you a sample of an element and asks you to classify it based on its properties. You find that this substance is a poor conductor of electrical current, a poor conductor of heat, and its appearance is dull and brittle. Based on these observations, you can determine that the substance is a __________.

• nonmetal

• semimetal

• metal

• none of the above

Which material BEST conducts heat and electricity?

• metal

• plastic

• rubber

• wood
