100
The ability or tendency to float in water or air or some other fluid?
What is buoyancy?
100
The degree of compactness of a substance.
What is density?
100
True or False: Water can have different densities.
What is True?
100
The state of matter that has a fixed volume and shape with particles that are close together and fixed into place.
What is a solid?
100
A gas that weighs less than air.
What is helium?
200
True or False: All solid objects are denser than liquids.
What is False?
200
Which object is more dense, lead or styrofoam?
What is lead?
200
This type of water can float on fresh water.
What is salt water?
200
The state of matter in which atoms or molecules can move freely while remaining in contact with one another.
What is a liquid?
200
Two states of matter that are fluids.
What are liquids and gases?
300
The force that pushes up that makes objects buoyant.
What is buoyant force?
300
The force than pushes down that makes dense objects heavy.
What is gravity?
300
DAILY DOUBLE!!!! Explain the relationship between density and buoyancy.
What is density determines whether or not an object floats (is buoyant) in a liquid, given its mass?
300
The state of matter that is composed of molecules in constant random motion and has no fixed shape and will take on the shape of the space available.
What is a gas?
300
Pressure is almost twice as heavy here than in water.
What is on land?
400
The principle that states "Buoyant force is equal to the weight of water an object displaces".
What is Archimedes' Principle?
400
The term used to explain why one object floats and another object sinks, even though they have the same mass.
What is density?
400
An object that is less dense than salt water, but more dense than fresh water.
What is a potato?
400
The substance that is less dense as a solid, than when its a liquid.
What is water?
400
The type of buoyancy where the gravitational force is more than the buoyant force.
What is negative buoyancy?
500
The term for what happens when an object enters a liquid and the water level goes up.
What is displacement?
500
This divided by mass equals density.
What is volume?
500
Explain why adding salt to water makes water more dense.
What is more particles added to water makes the particles come closer together, and thus, more dense.
500
Helps to determine the state an object is in.
What is temperature?
500
The type of buoyancy where the buoyant force is more than the gravitational force.
What is positive buoyancy?
