Density

Which property of matter is determined by dividing its mass by its volume?

• elasticity
• buoyancy
• density
• viscosity

Mercury is a metal that is liquid at room temperature and has a density of 13.5 g/cm3.  Which of these metals would sink below the mercury if dropped into a container of mercury?

• gold (density=19.3 g/cm3)
• lead (density=11.4 g/cm3)
• iron (density=7.9g/cm3)
• aluminum (density=2.7g/cm3)

A brick sinks in water while a wooden block of the same size floats.  This is because the brick has a

• lower volume than the wooden block
• lower density than the wooden block
• higher volume than the wooden block
• higher density than the wooden block

What is the density of a liquid that has a mass of 27g and a volume of 30ml?

• 0.9 g/ml
• 3 g/ml
• 57 g/ml
• 810 g/ml

What is the density of a substance that has a mass of 30g and a volume of 6 liters?

• 24 g/l
• 5 g/l
• 36 g/l
• 180 g/l

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

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
