​States of Matter

Multiple Choice

A student classifies the objects shown based on their physical properties. Which property cannot be used to classify these objects into more than one group? (5.5A)

• Magnetism

• Mass

• Electric Conductivity

• Solubility in Water

Magnetism

• ​A force that attracts or repels magnetic materials

• Some examples of magnetic materials are:

  • Iron fillings

  • Paper Clips

Multiple Choice

Some students investigate the properties of four objects using a hand lens, a magnet, and a beaker containing water. Their observations are recorded in the table. Which statement identifies a property that could be used to classify these objects into two different groups? (5.5A)

• 
  Density can be used to separate objects that sink in water from objects that do not.

• Magnetism can be used to separate objects that are attracted by a magnet from objects that are not.

• Solubility can be used to separate objects that dissolve in water from objects that do not.

• Physical state can be used to separate objects that are solids from objects that are not.

Relative Density

• Floating or sinking when compared to water.

Density

A measure of how tightly packed and how heavy the molecules are in an object.

The amount of matter within a certain space.

Multiple Choice

The table lists some properties of four different samples of matter. Which two samples could be glass and saltwater? (5.5A)

• Samples 1 and 2

• Samples 1 and 3

• Samples 3 and 4

• Samples 2 and 3

Multiple Choice

Objects that blow into a swimming pool or that are dropped into the pool by swimmers need to be removed. These objects include foam cups, keys, and coins. Which of the following explains a useful method for removing some of these objects? (5.5A)

• The keys and coins are less dense than water, so they can be easily picked up off the bottom of the pool by divers.

• 
  The foam cups have the same density as water, so they can crumbled up for removal by the pool filter.

• The foam cups are less dense than water, so they can be removed from the surface with a pool cleaning net.

• The keys and coins have the same density as water, so they can washed away when the pool is drained.

Multiple Choice

Which of these is not soluble in water?

• Oil

• Honey

• Salt

• Sugar

Multiple Choice

A teacher mixes a white powder into a beaker of water. The powder cannot be seen in the water. The teacher then heats the mixture until the water evaporates and the powder can be seen again. Which property of the powder is the teacher demonstrating? (5.5A)

• Conductivity

• Solubility

• Relative Density

• Mass

Multiple Choice

A student reads the label on the bottle of salad dressing shown here. Why would the student shake the salad dressing well before using it? (5.5A)

• Vinegar and Oil easily form a solution

• Vinegar and Oil are both liquids

• Vinegar and Oil contain water

• Vinegar and Oil have different densities

Multiple Choice

A student is asked to design a sleeve for a cup that will insulate thermal energy and not feel hot to the touch when the cup is filled with hot liquid. The student has four materials to choose from. Which of these materials is least useful as an insulator? (5.5A)

• Cardboard
