6th Grade Unit 2: Properties of Matter

A student is examining an object in science class. It is a solid, does not conduct, malleable but not ductile, and it is a shiny silver color.

The sample is most likely----

• Nonmetal

• Metalloid

• Metal

• Semi-Conductor

Which of the following best replaces X in the table above?

• Chemical composition

• Malleability

• Reactivity

• Oxidation

Copper is a common metal. Which of the following properties does this metal most likely have?

• Low conductivity, low malleability, and low luster

• High conductivity, high malleability, and low luster

• Low conductivity, high malleability, and high luster

• High conductivity, high malleability, and high luster

the capability of a substance to be molded and shaped, or hammered into sheets without breaking is known as --

• ductility

• conductivity

• malleability

• luster

How is "luster" used as a physical characteristic of elements listed as metals on the periodic table of elements?

• Luster means that metals can be pulled and twisted into thin wires.

• Luster means that metals can be pounded into sheets without breaking

• Luster means that metals can be considerably shinier than non-metals

• Luster is not one the physical characteristics used to classify metals

The volume of an unknown liquid is shown in the graduated cylinder. The mass of the liquid is 105 grams.

What is the density of the unknown liquid?

• 3500 g/ml

• 0.33 g/ml

• 3.0 g/ml

• 3.3 g/ml

What is the density of the rock sample shown in the illustration?

• 0.2 g/cm3

• 40 g/cm3

• 5.0 g/cm3

• 1.43 g/cm3

A student needs to find he density of a cube. Each side of the cube measures 3cm and the mass of the cube is 12 grams.

What is the approximate density of the cube?

• 0.4 g/cm3

• 2.25 g/cm3

• 4.0 g/cm3

• 36 g/cm3

A student decided to find the density of her house key to try and identify the type of metal from which it is made. She sound the volume of the key to be 5 mL and he mass to be 39.5g.

Using the chart above, from which type of metal is the key made?

• Aluminum

• Steel

• Copper

• Gold

A streak test used to identify minerals requires---

• studying crystals with a magnifying glass

• scratching the mineral with an iron nail identifying the color of the powdered material

• identifying the color of the powdered mineral

• observing how it reflects light from its surface
