Density Concepts Worksheet

What is density?

• The amount of mass in a given volume

• The amount of volume in a given mass

• The amount of weight in a given size

• The amount of space an object takes up

If a bowling ball and a basketball are about the same size, but the bowling ball feels much heavier, what property explains this difference?

• Color

• Density

• Shape

• Temperature

Why might some objects float while others sink, according to the concept of density?

• Objects with lower density than water float, while those with higher density sink

• Objects with higher temperature float, while those with lower temperature sink

• Objects with larger volume float, while those with smaller volume sink

• Objects with more color float, while those with less color sink

Why is the basketball less dense than the bowling ball?

• It contains more resin particles.

• It contains air particles that are spread far apart.

• It is heavier than the bowling ball.

• It has a smaller volume.

How is density calculated?

• Mass multiplied by volume

• Mass divided by volume

• Volume divided by mass

• Volume plus mass

Which of the following units are equivalent when measuring volume?

• 1 cm³ = 1 mL

• 1 g = 1 mL

• 1 cm = 1 mL

• 1 g = 1 cm³

What is the typical unit for mass in chemistry?

• Liters (L)

• Grams (g)

• Meters (m)

• Milliliters (mL)

What is the density of aluminum as given in the material?

• 2.70 g/cm³

• 1.30 g/cm³

• 3.51 g/cm³

• 1.75 g/cm³

Given a small aluminum bar with a mass of 1,755 g and a volume of 650 cm³, use the density equation to calculate its density.

• 2.70 g/cm³

• 1.75 g/cm³

• 3.50 g/cm³

• 650 g/cm³

Which of the following best describes why density is considered an intrinsic property?

• Because it changes when the amount of material changes

• Because it depends on the shape of the object

• Because it does not change based on the amount of material you have

• Because it is only found in metals
