Liquid Density

Which liquid is the least dense?

• oil

• water

• syrup 

• plastic bottle

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

Why do the liquids form different layers?

• They have different densities.  

• They have different masses.  

• They have different volumes.  

• They are different temperatures.

If you poured 3 liquids that do not mix how could you tell which one is the most dense?

• The liquid on top

• The liquid in the middle

• The liquid at the bottom

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 

Why do ice cubes float in a  glass of water?

• the ice cubes are more dense than the water

• the water is more dense than the ice cubes

• the water is more dense than the glass

• the ice is more dense than the glass

An irregularly shaped piece of gold was lowered into a graduated cylinder holding a volume of water equal to 17 ml. The height of the water rose to 20 ml. If the mass of the gold was 27 g, what was its density?

• 9 g/mL

• 10.5 g/mL

• 6.5 g/mL

• 8 g/mL

What two types of measurements make up DENSITY? 

• Mass and Volume

• Temperature and Mass

• Grams and Centimeters

• Volume and Weight

Why do objects sink or float in H₂O? 

• Because their densities are higher or lower than compared to water

• Because their densities are using gravity to pull down

• Because their densities are heavier or lighter

• Because their mass and volumes are equal
