Density Quiz

What is the definition of density?

• Mass divided by volume

• Mass multiplied by volume.

• Volume divided by mass.

• Weight divided by volume.

How is density calculated?

• mass/volume

• mass + volume

• mass - volume

• mass * volume

What is the density of a solid with a mass of 50 grams and a volume of 10 cubic centimeters?

• 0.5 grams per cubic centimeter.

• 5 grams per cubic centimeter

• 10 grams per cubic centimeter.

• 20 grams per cubic centimeter.

A solid has a mass of 100 grams and a volume of 20 cubic centimeters. What is its density?

• 5 grams per cubic centimeter

• 50 grams per cubic centimeter.

• 2 grams per cubic centimeter.

• 10 grams per cubic centimeter.

Which has a higher density: a solid with a mass of 200 grams and a volume of 50 cubic centimeters, or a solid with a mass of 150 grams and a volume of 40 cubic centimeters?

• The solid with a mass of 200 grams and a volume of 50 cubic centimeters has a higher density.

• The density cannot be determined without knowing the material of the solids.

• Both solids have the same density.

• The solid with a mass of 150 grams and a volume of 40 cubic centimeters has a higher density.

What is buoyancy?

• The force of friction on an object.

• The force of gravity on an object.

• Upward force exerted by a fluid on an object

• Downward force exerted by a fluid on an object.

How does the density of an object affect its buoyancy?

• The density of an object affects its weight but not its buoyancy.

• The density of an object determines whether it will float or sink in a fluid.

• The density of an object has no effect on its buoyancy.

• The density of an object determines its color.

A wooden block has a density of 0.6 g/cm³. Will it float or sink in water?

• float

• stay suspended

A metal ball has a density of 8 g/cm³. Will it float or sink in water?

• float

• suspend

• hover

• sink

A plastic bottle has a density of 1.2 g/cm³. Will it float or sink in water?

• sink

• disappear

• hover

• float
