Properties of Matter

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

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 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

Which statement correctly represents a mineral with a hardness of 7?

• The mineral cannot be scratched by apatite, but can be scratched by feldspar.

• The mineral can be scratch calcite, but cannot scratch apatite.

• The mineral can scratch apatite and every mineral with a hardness scale number higher than 7.

• The mineral can scratch apatite and every mineral with a hardness scale number lower than 7.

Ms. Cruz set up lab tables for an experiment. At each lab table, she placed a sample of a mineral. The students are asked to record descriptions of this mineral in their journals. The words used were; shiny, sparkly, and silvery. What physical property was being tested?

• Color

• Luster

• Streak

• Hardness

Scratching an object with your fingernail is a way of testing an object's--

• Weight

• Temperature

• Hardness

• Magnetism

The ability of one mineral to scratch another mineral is determined by the mineral’s —

• Luster

• Streak

• Color

• Hardness

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

substances that have the physical properties of luster, conductivity, and malleability; may appear in all three states of matter

• metalloids

• metals

• mass

• nonmetals
