Brain Density

Density measures an object's:

• Compactness

• Mass

• Size

• Material

Mass is a measure of the

• Type of atoms in

• Amount of matter in

• Size of

• Shape of

Which term refers to the amount of physical space an object takes up?

• Volume

• Mass

• Density

• Displacement

Why does lowering the temperature of an object increase its density?

• Because the mass decreases

• Because the mass increases

• Because the particles move closer together

• Because the particles spread farther apart

A sample of copper has a mass of 50 g and a volume of 5 cm^3. What is its density?

• 0.1 g/cm^3

• 10 g/cm^3

• 45 g/cm^3

• 55 g/cm^3

An object's density is 15 g/cm^3 and its volume is 3 cm^3. What is its mass? Multiply instead of divide for Mass

• 45 g

• 18 g

• 12 g

• 5 g

Which of these substances has the lowest density?

• Water vapor

• Boiling water

• Room-temperature water

• Ice

You plan to use the water displacement method to determine if a ring is pure silver. Each of these tools is required, EXCEPT:

• A balance

• A stopwatch

• A measuring cup filled with water

• A density of elements chart

An object submerged into 50 cm^3 of water raises the water level to 65 cm^3. The mass of the object is 30 g. What is its density?

• 450 g/cm^3

• 45 g/cm^3

• 15 g/cm^3

• 2 g/cm^3
