Matter
anything that has mass and takes up space
What is matter?
A change in matter that doesn't create a new substance.
What is Physical change?
A substance containing 2 or more elements, bonded together is called this.
What is a compound?
A combination of 2 things in uniform composition
What is a solution/homogeneous mixture?
the amount of matter something has
What is mass?
A property that can be observed only by changing the identity of a substance.
What is a chemical property?
Aluminum, iron, carbon, neon, and calcium are examples of what
What are elements?
This type of mixture is different throughout. Fruit salad and granite are examples of this.
What is a heterogeneous mixture?
The amount of space an object takes up.
What is Volume?
Flammability and reactivity are examples of this
What is chemical properties?
H20 (water) and CO2 (carbon dioxide) are examples of this.
What is a compound?
This type of mixture is the same throughout.
What is a homogeneous mixture?
this is the temperature at which a substance goes from a liquid to a gas
What is boiling point?
Burning a candle is this type of change.
What is chemical change?
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?
this is the relationship between mass and volume
What is density?
A state change is this type of change
What are physical changes?
Draw a particle diagram representing an element
Should be all of the same atoms
This type of mixture is easy to separate back into its original components.
What is heterogeneous?
All matter is made up of these.
Provide three examples of physical properties.
What are color, volume, length, mass, weight brittleness, density, ductility, flexibility, malleability, solubility, specific heat, conductivity, viscosity, hardness?
Draw a particle diagram of a compound
Italian dressing is an example of this type of heterogeneous mixture
What is suspension?
Provide an example of something that is NOT made of matter.
What is time, heat, energy, light, sound, thoughts?
Provide three signs of a chemical change.
What are change in color, formation of a gas, formation of a precipitate, change in odor, change in temperature, burning, production of light
Pure substances have _________ AND __________ composition
What is uniform and definite?
Type of mixture with particles that are larger than those in solution, but still too light to settle out
What is a colloid?
