What two properties do you need to find density?

• Volume and weight

• Mass and volume

• Only volume

• Only mass

If an object sinks in water than it is (a)   than water and

If an object floats in water then it is (a)   than water.

The formula for finding density is:

•  

  The volume divided by the mass.

• The mass multiplied by the volume.

• The mass divided by the volume.

• The volume multiplied by the mass.

What are the units of measuring Density?

• g/cm³

• kg/m³

• kg/L

• g/m

The density of water is

• 13600 kg/m³

• 1000 kg/m³

• 7800 kg/m³

• 625 kg/m³

What is the formula for calculating density?

Which of the following substances is most likely to float on water?

• Iron

• Wood

• Gold

• Lead
