Density

What two types of measurements make up DENSITY? 

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

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

• 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

If an object has a density of .6 g/mL and you put it into water, will it sink or float?  

• sink
• float

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

• 8 g/ml

• 2 g/ml

• 1/2 g/ml

• 24 g/ml

What units are used to measure mass?

• g
• cm³
• g/cm³
• cm³/g

What is the formula for density?

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

Which units of measurement are used for volume?

• grams
• centimeters
• grams/milliliter
• milliliter

An object is is placed into 45 mL of water. The water rises to 48 mL. What is the volume of the object?

• 3 mL

• 93mL

• 8 mL

• 83 mL

There are 4 objects listed with their densities. Which of the following will float on water? (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

If I cut a block of gold in half, what happens to its density?

• Density is cut in half.

• Density stays the same.

• Density doubles.

• Density cannot be determined.
