Basics
This property of matter describes how much "stuff" is packed into a given space.
What is density?
Density=_____/______
What is mass divided by volume?
Brick has a mass of 6,000g and a volume of 2,000cm3.
What is 3.00g/cm3?
Block of wood has density of .2g/cm3
What is floating?
cm3
What is units of volume?
The two fundamental measurements needed to determine an object's density are its mass and its what?
What is volume?
Density x Volume=_________
What is mass?
A liquid has a mass of 24g and density of 2.0g/mL. It's volume is this....
What is 12 mL?
Item has a density of 2.5g/cm3
What is sinking?
Density units
What is g/mL or g/cm3
A common tool used to measure mass.
What is a balance or scale?
What is the approximate density of pure water at room temperature, which is often used as a reference point for floating or sinking?
What is 1 g/cm³ (or 1 g/mL)?
A metal has a volume of 15cm3 and density of 3.0g/cm3. It's mass would be....
What is 45 g?
Steel block has a density of 8.1g/cm3
What is sinking?
Can you find the density of a square? How, or explain why not.
What is no? A square is not 3 dimensional, a cube is, so you can only find the density of a cube.
A large log floats on water, while a small pebble sinks. Explain this phenomenon in terms of density.
What is the log floats because its overall density is less than water, even though parts of it might be denser, while the pebble sinks because its density is greater than water?
A liquid has a mass of 60g and volume of 30mL, its density is....
What is 2.0g/mL?
This happens to an object if its density is exactly the same as the liquid it's placed in.
What is suspended (or stays in the middle)?
Mass per volume units (list both answers for solids and liquids).
What is density or g/ml or g/cm3? Remember liquids and solids have different units for volume.
Explain why a feather and a small rock, even if they have the same mass, will have very different densities.
What is because they occupy vastly different volumes, with the rock having a smaller volume for the same mass?
A shoe box has a volume of 500.00cm3 and mass of 750.0 grams. Its density is...
What is 1.5 g/cm3?
An object with a mass of 20g and a volume of 20mL is placed in water.
What is suspending?
What units would you use to describe what fills a ballast tank on a submarine?
What is g/mL? Remember: Air and Water fill the tanks and they are both fluids (not solids) so you use g/mL.
