Properties of Matter 1

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
• 3, 4, 2, 1, 
• 4, 3, 1, 2

Which box has a higher density?

• A

• B

• They are the same

What is the formula for density?

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

Fred has a toy car. It has a mass of 9g and a volume of 3cm³. What is its density?

• 3 g/cm³
• 1/3 g/cm³
• 27 g/cm³
• 39 g/cm³

An object is placed into 45 mL of water. The water rises to 50 mL. What is the volume of the object?

• 50 mL

• 5 mL

• 2250 mL

• .9 mL

There are 4 objects listed with their densities. Which of the following will float on water? (Water's density is 1.0 g/cm3) (SELECT 2)

• Object A:

  0.7 g/cm3

• Object B:

  1.2 g/cm3

• Object C:

  0.25 g/cm3

• Object D:

  11.4 g/cm3

The amount of space something takes up

• density

• mass

• volume

• matter

True or False:  The density of a specific type of material never changes.

• true

• false

 Density is...

• the amount of matter in an object

• the amount of matter packed into a given space

• the amount of space an object takes up

• the weight of an object

Look at this image.  Which object has the LOWEST density in water? How do you know? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball
