What are the characteristic properties of matter?
|
Magnetism, denisty and bouyancy are all characteristic properties of matter.
|
|
|
Why do scientists use characteristic properties of matter?
|
Scientists use characteristic properties to classify different substances.
|
|
|
What is magnetism?
|
Magnetism is the force of attraction betwen a magnet and a magnetic object or substance.
|
|
|
What is a megnet?
|
A magnet is an object that attracts iron or objects or substances that contain iron.
|
|
|
What surrounds all magnets?
|
All magnets are surrounded by a magnetic field.
|
|
|
What is a magnetic field?
|
A magnetic field is a force that can push or pull on magnetic objects from a distance.
|
|
|
How is a magentic field produced?
|
The magnetic field surrounding a magent is produced by moving charged particles (electrons) within the atoms that make up that magnet.
|
|
|
How do you determine the density and volume of an object?
|
You can determine the density of an object by weighing it to find its mass and using water displacement to identify its volume.
|
|
|
What is the formula for finding density?
|
The formula for finding density is D=M/V.
|
|
|
What does the Archimedes Principle state?
|
The Archimedes Principle states that an object in water is buoyed upward by a force equal to the weight of the water it displaces. The weight of the water displaced by the object is equal to the weight the object "loses" in water.
|
|
|
All objects in water are subjected to what force?
|
All objects in water are subjected to the force of buoyancy, even when they don't float.
|
|
|
What two things will determine whether the force of buoyancy will be enough to make the object float?
|
An object's density and the amount of water it displaces will determine whether the force of buoyancy will be enough to make the object float.
|
|
|
How can you make an object float?
|
Objects can be made to float by making their density less than the density of water.
|
|
|
How can you make an object that sinks become buoyant?
|
An object that sinks can become buoyant when its density is changed.
|
|
|
Buoyancy and density interact to do what?
|
Buoyancy and density interact to make an object float or sink.
