Multiple Choice

__ is the amount of matter within a certain volume.

• Density

• Mass

Multiple Choice

The tool used to measure the mass of a substance or object is a ______________.

• balance
• graduated cylinder
• ruler
• thermometer

Multiple Choice

Do all objects have the same density?

• yes

• no

Multiple Choice

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Multiple Choice

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

Multiple Choice

What units are used to measure Density?

• cm³/g
• g
• g/cm³
• cm³

Dropdown

The density of water is ​

Select answer

g/cm³

Multiple Choice

When the density of a substance is lower than the density of water the substance the substance does what in water?

• sink

• float

Multiple Choice

When the density of a substance is greater than the density of water the substance the substance does what in water?

• sink

• float

Multiple Select

Which of the following objects will sink in water? (Check all that apply)

• Object A (Density = 1.5 g/mL)

• Object B (Density = .5 g/mL)

• Object C (Density = 1.0 g/mL)

• Object D (Density = 2.0 g/mL)

Multiple Select

Which of the following objects will float in water? (Check all that apply)

• Object A (Density = 1.5 g/mL)

• Object B (Density = .5 g/mL)

• Object C (Density = 0.87 g/mL)

• Object D (Density = 2.0 g/mL)

Match

Match the following

• Maple Wood

• Concrete

• Silver

• Ice

• Blood

​Remember! D=m/v

m=30g v=5 g/cm³
So, D= 30g/5 g/cm³
D= 6 g/cm³
