Density Quiz

What is the definition of density?

• The amount of space an object occupies

• The mass of an object per unit volume

• The weight of an object in air

• The volume of an object per unit mass

Which of the following is a unit of density?

• Kilogram (kg)

• Meter (m)

If an object floats in a liquid, what can be inferred about its density?

• It has a higher density than the liquid

• It has the same density as the liquid

• It has a lower density than the liquid

• Density does not affect floating

What happens to objects with higher densities than the liquid they are placed in?

• They float on the surface

• They dissolve in the liquid

• They sink to the bottom

• They change color

What is the formula for density?
