Grade 8 Fluids

Density is...

• the amount of mass in an object
• the amount of space an object takes up
• the amount of mass in a given space
• the weight of an object

What is the formula for density?

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

What units can be used to express density?

• g/mL
• grams
• millimeters
• milliliters

True or False:  The density of a specific type of material never changes.  

• True
• False

If the density of a bar of gold is 19.3 g/cm³and you cut it into 4 pieces,  what is the density of each piece of gold?  

• 4.825 g/cm³
• 9.65 g/cm³
• 19.3 g/cm³
• 38.6 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

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

• sink
• float

Which liquid is the most dense?  

• oil
• water
• syrup
• plastic bottle

Which liquid is the least dense?

• oil
• water
• syrup
