Density
Sink or Float
Pressure
100
D= volume over mass
What is the density equation?
100
Because ice has a lesser density than water, it will do this.
What is float?
100
A unit of pressure is called this?
What is a pascal?
200
g/cm3
What is the units for expressing the density of a solid?
200
A ship will float because of this?
What is its hollow shape which cause it to have more volume and surface area?
200
Air pressure does this as elevation increases.
What is decreases?
300
This is less dense than air?
What is helium?
300
Because the buoyancy force is EQUAL to the weight of the object.
What is the object will float?
300
Water pressure does this as your depth in water increases.
What is increases?
400
The mass per unit volume of a substance.
What is density?
400
It acts in an upward direction.
What is buoyancy force?
400
Even though air pressure is so great, we are not crushed because of this.
What is because the pressure inside and outside of our bodies is equal and balanced?
500
This is a substance that is NOT dense and used as a floating device such as a raft.
What is wood?
500
Air bubbles will rise to the surface because they are this.
What is air bubbles are less dense than air?
500
This is force per unit of area.
What is pressure?
