Density Revision

What is the formula for density?

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

What two types of measurements make up DENSITY? 

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

Which liquid is the least dense?

• oil
• water
• syrup 
• plastic bottle

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

• 8 g/cm³
• 2 g/cm³
• 1/2 g/cm³
• 24 g/cm³

Frank has a paper clip. 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

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

What is the volume of Object X?

• 10.0 cm³
• 15.0 cm³
• 20.0 cm³
• 25.0 cm³

What unit is used to measure mass?

• g

If an object has a density of 3.6 g/cm3 and you put it into water, will it sink or float?  

• sink
• float

Why do some substances float on water?

• they are warmer than water
• they are cooler than water
• they are more dense than water
• they are less dense than water
