In a lab, a scientist has a beaker of pure water and a battery at the bottom. When he places a lightbulb in the water, the light bulb does nothing. He then adds salt to the water, and places the lightbulb in the water with salt in it, and the lightbulb lights up. What physical property was produced in the water when salt was added to the water?

• solubility

• flammability

• malleability

• conductivity

The table below shows the properties of four unknown liquids. Each sample is in its own beaker. A student adds equal amounts of substance K to each beaker.

If substance K has a known density of 6.4 g/ml, in which liquid will K sink.

• W and X

• X and Z

• W and Y

• Y and Z

A student determines the volume, density, and boiling point of three colorless liquids and lists them in the table. Could any of the liquids be made of the same substance? Why?

• Liquids 1 and 2 could be the same substance because they have the same density

• Liquids 1 and 3 could be the same substance because they have the same volume

• Liquids 1, 2, and 3 could be the same substance because they are all clear liquids

• None of the liquids could be the same substance because they have different combinations of density, and boiling points

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
