When panning for gold, a miner scoops up gravel, rocks, and dirt, and then washes the mixture with water, leaving the gold behind. What is one reason the gold is easily separated from the gravel, rocks, and dirt?
A. The gold is easily separated because the mixture is a pure substance. This means it is easily separated by physical means.
B. The gold is easily separated because the mixture is a homogeneous mixture. This means it is easily separated by physical means.
C. The gold is easily separated because the mixture is a heterogeneous mixture. This means it is easily separated by physical means.
D. The gold is easily separated because the mixture is a solution. This means it is easily separated by physical means.
C. The gold is easily separated because the mixture is a heterogeneous mixture. This means it is easily separated by physical means.

- Breaks apart easily when hit with a hammer
- Dull appearance
- Low melting point
- Unable to conduct electricity
- A. The students tested a metalloid because the physical properties are of both a metal and nonmetal.
- B. The students tested a metal because the physical properties describe metals.
- C. The students tested a nonmetal because the physical properties describe nonmetals.
D. The students need to conduct additional investigations to determine more physical properties before the unknown element can be classified.
C. The students tested a nonmetal because the physical properties describe nonmetals.

The Periodic Table can be broken into three different sections. In which section would you expect to find an element that is a semiconductor, shiny, and brittle?
A. An element that is a semiconductor, shiny, and brittle would be a metal; therefore, it can be found in Section 1.
B. An element that is a semiconductor, shiny, and brittle would be a metal; therefore, it can be found in Section 3.
C. An element that is a semiconductor, shiny, and brittle would be a metalloid; therefore, it can be found in Section 2.
D. An element that is a semiconductor, shiny, and brittle would be a metalloid; therefore, it can be found in Section 3.
D. An element that is a semiconductor, shiny, and brittle would be a metalloid; therefore, it can be found in Section 2.

What state of matter is this image showing?
Gas
3
What is happening to the molecules as the flame heats the water? 
A. As heat energy is taken away, the volume of the water becomes more definite.
B. The heat energy causes the molecules to move more slowly and clump together, taking up less space.
C. Heat energy causes the molecules to move faster, so they are farther apart and take up more space.
D. The molecules grow larger and take up more space, so the volume increases.
C. Heat energy causes the molecules to move faster, so they are farther apart and take up more space.
