Density

What two types of measurements make up DENSITY? 

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

Why do the liquids form different layers?

• They have different densities.  
• They have different masses.  
• They have different volumes.  
• They are different temperatures.  

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

• 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 0.6 g/mL and you put it into water, will it sink or float?

• sink

• float

What is the formula for density?

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

Adonis has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL

• 7 g/cm³

• 28 g/cm³

• 1/7 g/cm³

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

• sink
• float

Dream 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

An object should float in a liquid if it is 

• Denser than the liquid 
• Less dense than the liquid
• Lighter than metal
•  Shaped like a ball 

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
