6S Chapter 9: Classifying Matter

What are the three components of an atom?

• Carbon, hydrogen, and helium

• Neutron, proton, and electron

• Isotopes, nucleus, and electrons

• Neutron, proton, and atoms

Why are large ships able to float on water?

• Mass

• Plasma

• Sublimation

• Buoyancy

How is the periodic table organized?

• Alphabetically

• By color

• By density

• By atomic number

How is the volume of a regularly shaped object calculated?

• By dividing its mass by its weight

• By multiplying its density by its weight

• By multiplying its length, width, and height

• By placing the object in a liquid to see how much it floats

What is the measure of the speed at which particles move in a material?

• Temperature

• Atomic Speed

• Sublimation

• Boiling Point

What causes particles to slow down and begin to condense?

• Decrease in heat

• Increase in heat

• Decrease in pressure

• Increase in sublimation

Temperature at which a liquid becomes a gas.

• Melting Point

• Boiling Point

• Freezing Point

• Icing Point

Where can the majority of plasma be found?

• Bottom of the ocean

• Volcanoes

• Stars

• In science labs

What happens to the molecules of a liquid when it reaches its boiling point?

• Evaporation

• Sublimation

• Suspension

• Vaporization

What is the difference between a dilute solution and a saturated solution?

• In a dilute solution, a substance is evenly dissolved. In a saturated solution, a substance cannot dissolve any more.

• A dilute solution is a chemically dissolved solution. A saturated solution is a physically dissolved solution.

• A dilute solution is when a gas is dissolved in other gases. A saturated solution is when a liquid is dissolved in other liquids.

• They both mean the same thing. The science people want to confuse you.
