Density and Buoyancy

What describes how much mass is in a given volume?

• Matter
• Density
• Buoyancy
• Displacement

What is the equation to calculate density?

• D = M x V
• D = L x W x H
• D = M / V
• D = M + V

What is one thing that the density of a material depends on?

• The shape of the object
• How colorful the atoms are
• The texture of the object
• How tightly the atoms are packed

A brick has a mass of 562 g and a volume of 43 cm3.  What is the density?

• 0.08 g/cm3
• 24,166 g/cm3
• 13.1 g/cm3
• 519 g/cm3

If the weight of an object is less than the buoyant force, the object will...

• Remain neutral
• Sink
• Float
• Shake

If an object’s weight is greater than the buoyant force, the object will...

• Remain neutral
• Sink
• Float
• Shake

If an ice cube is floating in water, water is exerting an upward force on the ice.  What force is pushing the ice cube down?

• Buoyancy
• Gravity
• Newtons
• Air Pressue

Who is the Greek scientist whose principle states that the buoyant force on an object in a fluid is equal to the weight of the displaced fluid?

• Socrates
• Galileo
• Plato
• Archimedes’

The density of four liquids are as follows:
Milk : 1.03 g/cm3
Baby Oil : 0.83 g/cm3
Honey : 1.42 g/cm3
Corn Syrup : 1.33 g/cm3 
If carefully poured into a density column with the most dense liquid on the bottom, and the least dense liquid on top, what would the order of the liquids be?

• Honey, Corn Syrup, Milk, Baby Oil
• Milk, Baby Oil, Honey, Corn Syrup
• Honey, Milk, Baby Oil, Corn Syrup
• Corn Syrup, Honey, Milk, Baby Oil

Does gas have density?

• Yes
• No
• Sometimes
• I have no idea
