anything that has mass and takes up space
What is matter?
This substance has a definite shape and define volume.
What is a soild?
This results in a new substance and is permanently changed
What is a Chemical change?
A substance containing 2 or more atoms, bonded together is called this.
What is a molecule?
A combination of 2 things in uniform composition
What is a solution/homogeneous mixture?
the amount of matter something has
What is mass?
This has no definite shape, but does have a definite volume
What is a Liquid?
A change in matter that involves a change in a physical property but doesn't create a new substance
What is Physical change?
H20 (water) and CO2 (carbon dioxide) are examples of this as they are made up of different elements bonded together.
What is a compound?
Blood is an example of this this type pf mixture.
What is a homogeneous mixture?
The amount of space an object takes up.
What is Volume?
Atoms packed closely together in this state and they have high density
What is a solid?
A property that can be observed only by performing a chemical change
What is a chemical property?
What would a diagram of an element look like...
Should be all of the same atoms
One or more atoms bonded together.
What is a molecule?
this is the temperature at which a substance goes from a liquid to a gas
What is boiling point?
If enough heat is added to a liquid it become this state.
What is a gas?
A phase change is this type of change
What are physical changes?
A diamond is an example of this.
What is a pure substance?
This type of mixture is easy to separate back into its original components.
What is heterogeneous?
this is the relationship between mass and volume
What is density?
When heat is added to a solid, it becomes this state of matter
What is a liquid?
Two types of changes matter undergoes:
What are physical & chemical ?
Type of pure substance that can be separated chemically?
What is compouds?
This type of mixture is more difficult to separate because you cannot see the individual pieces.
What is homogeneous?
When a gas is heated to a very high temperature, electrons are "torn off" the atoms.
What is intensive plasma?
If heat is removed, a liquid will become this state
What is a solid?
These are used to study the properties of matter.

What are elements?
This type of mixture is the same throughout. Lemonade and milk are two examples of this.
What is a homogeneous mixture?
A pure substance that CANNOT be broken down chemically
What are elements?
state of matter that is compressible
What is a gas?
Flammability and reactivity are examples of this
What is chemical properties?
Describe a diagram of a compound
Should be at least two different types of atoms bonded together
This type of mixture is different throughout. Fruit salad and granite are examples of this.
