Understanding Density and Mass

What is the common misconception about the weight of a ton of bricks compared to a ton of feathers?

• Bricks weigh more because they are denser.

• Bricks weigh more because they are larger.

• They weigh the same because both are a ton.

• Feathers weigh more because they are lighter.

What does density measure?

• The weight of an object.

• The mass per unit volume of an object.

• The mass of an object.

• The volume of an object.
