Practice Density Lab Quiz

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 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

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock? (d = m/v )

• 7 mL

• 7 g/cm³

• 28 g/cm³

• 1/7 g/cm³

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

• sink
• float

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

• sink
• float

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 

Archimedes used density to discover if the crown of gold was real because

• Substances have their own unique densities

• Substances can change densities depending on their size

• Substances can change densities depending on their mass

• Substances can change densities depending on their volume

Why does ice float?

• Liquid water is less dense than solid water.
• Solid water is less dense than liquid water.
• Gaseous water is less dense than solid water.
• Liquid water is less dense than gaseous water.

Helium balloons rise on earth because

• helium is less dense than air
• helium is more dense than air
• helium is cooler than air
• helium is warmer than air

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
