Physical

Matthew has six cubes of different materials. Each cube has a mass of 10 grams (g). Matthew sorts the cubes into two groups using one physical property.

Which physical property did Matthew most likely use to sort the cubes into two groups?

• Density

• Magnetism

• Melting point

• Electrical conductivity

Imagine that the block shown below is made of pure gold.

If Ana cuts this block into two equal pieces, which of these statements best describes the pieces?

• The mass of each piece is the same as that of the original block

• The weight of each piece is the same as that of the original block

• The density of each piece is the same as that of the original block.

• The volume of each piece is the same as that of the original block.

The graph compares the density, in grams per cubic centimeter (g/cm3) , of four different substances.

Based on information from the graph, which of the following best compares the physical properties of two of the substances?

• Substance X has less mass than substance Y has.

• Substance W has less volume than substance X has.

• Substance Y would have less mass than substance Z would have if they had the same volume.

• Substance Z would have less mass than substance W would have if they had the same volume.

Look at the two pictures below. They show what happened when two solid blocks were each put in a jar containing a liquid.

Based just on what you can see in the pictures, what can you say about the blocks and the jars?

• The liquid in the jars must be water.

• The block in jar 1 weighs more than the block in jar 2.

• The block in jar 1 is floating lower in its liquid than is the block in jar 2.

• The block in jar 1 must be made of metal and the block in jar 2 must be made of wood.

Density is the ratio of mass to volume. Troy listed the density of four metals at 20 °C.

If Troy has a 4-cm cube of each of these metals, which cube will have the greatest mass?

• Brass

• Gold

• Iron

• Lead
