The density of an object depends on these two factors
What is volume and mass
100
This is the upward force exerted by a fluid on an ohject.
What is the buoyant force
100
The force per unit of area applied on the surface of an object.
What is pressure
100
When the upward buoyant force on an object is less than the object's weight, then the net force moves the object in this direction.
What is downward

Where Ms. Pauley went on vacation this past summer.
What is the UK/England/Ireland/Scotland
200
This is the equation for density.
What is density= mass divided by volume
200
This is a material that can flow and has no definite shape.
What is a fluid
200
Pressure ____________ when a force is spread out over a larger area.
What is decreases
200
When an object isn't accelerating, the forces acting on the object are _________.
What is balanced
200
This is how Ms. Pauley likes her coffee.
with a little bit of cream, no sugar
300
This is the unit used to measure density.
What is g/cm3
300
This force opposes (opposite direction) the buoyant force.
What is gravity or weight
300
This is the unit with which pressure is measured.
What is a pascal
300
This is what is required for an object to float.
The overall density of the object must be less than the density of the liquid.
300
The age difference between Ms. Pauley and her youngest sibling.
What is 10 years
400
This can be used to measure the density of a liquid
What is a graduated cylinder
400
The pressure exerted by a fluid increases with depth. This, however, doesn't change with depth.
What is the buoyant force
400
This is the equation used to calculate pressure.
What is pressure = force divided by area
400
This is how a hot-air balloon can float.
The heat expands the particles in the balloon, making them less dense than the surrounding air.

Where Ms. Pauley went to college
What is Cal State Fullerton or Chico
500
This method can be used to measure the density of an irregular solid.
What is the displacement method
500
This "law" states that the buyoant force on an object is equal to the weight of the fluid the object displaces.
What is Archimedes' Principle
500
The pressure when 100 Newtons is applied over 25 square meters.
What is 4 pascals
500
A ship can float higher in the ocean water than in the river. This is why.
The ocean water is more dense than the river water.
