Understanding Density - Checkpoint

What is the definition of density?

• The amount of space an object takes up

• The mass of an object divided by its volume

• The weight of an object multiplied by its height

• The temperature of an object

Which state of matter usually has the highest density?

• Gas

• Liquid

• Solid

• Plasma

What is the formula for calculating density?

If you pour oil and water into a container, the oil floats on top. What does this tell you about the density of oil compared to water?

• Oil is denser than water

• Oil is less dense than water

• Oil and water have the same density

• Oil is heavier than water

A balloon filled with helium rises in air. Which statement best explains why?

• Helium is heavier than air

• Helium is less dense than air

• Helium is a solid

• Helium is a liquid

Which of the three blocks has the greatest density?

• A

• B

• C

If two objects have the same volume but different masses, what can be said about their densities?

• They have the same density.

• The object with the greater mass has a higher density.

• The object with the lesser mass has a higher density.

• Nothing can be said about their densities without knowing their specific volumes.

Match the property to its units.

• milliLiters (mL)

• Mass

• grams per milliLiter (g/mL)

• Density

• grams (g)

• Volume

If you cut a wooden block in half, each half would have

• Half the density of the original piece

• Twice the density of the original piece

• The same density as the original piece

• No density at all
