100
The tendency of an object to rise or float in water or air
What is buoyancy?
100
I found it!
What is Eureka?
100
total mass divided by total volume
What is average density?
100
a device used for measuring the density of a liquid

200
g/mL
What are the units of density?
200
a sinking rock
What is negative buoyancy?
200
The buoyant force on an object is equal to the weight of the fluid displaced by the object.

300
to move an object out of the way
What is displacement?
300
helps control the depth that submarines sink or float
What are ballast tanks?
300
a boat floats lower in this type of water
What is fresh water?
400
particles are very close together with little space between them.
What is density of particles in a solid?
400
A force that works against gravity
What is buoyancy?
400
the buoyant force on an object is less than the force of gravity on the object
What is sinking?
400
decreases density by being increased
What is volume?
400
a substance where the solid is less dense than the liquid form
What is ice?
500
the particles in a substance move farther apart as this increases
What is temperature?
500
The density of the object is equal to the density of the fluid
What is floating?
500
The buoyant force on the object is equal to the force of gravity on the object
What is floating?
500
increases density when increased
What is mass?
500
