Matter
anything that has mass and takes up space
matter
This phase has a definite shape and define volume.
soild
A change in matter that doesn't create a new substance.
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
solution/homogeneous mixture
This is the state change from a gas to a liquid.
condensation
the amount of matter something has
mass
This phase has no definite shape, but does have a definite volume
Liquid
A property that can be observed only by changing the identity of a substance.
chemical property
Aluminum, iron, carbon, neon, and calcium are examples of what
elements
This type of mixture is different throughout. Fruit salad and granite are examples of this.
heterogeneous mixture
Hot chocolate with marshmallows in it is an example of this type of matter.
heterogeneous mixture
The amount of space an object takes up.
Volume
Atoms packed closely together in this state and they have high density and can not be compressed
solid
Flammability and reactivity are examples of this
chemical properties
H20 (water) and CO2 (carbon dioxide) are examples of this.
compound
This type of mixture is the same throughout. Lemonade and milk are two examples of this.
homogeneous mixture
Dissolving sugar into sweet tea is which kind of change?
Physical change
this is the temperature at which a substance goes from a liquid to a gas
boiling point
If enough heat is added to a liquid it become this state.
gas
Burning a candle is this type of change.
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.
homogeneous
Copper turning green such as on pennies or the Statue of Liberty is an example of this type of change.
chemical change (oxidation)
How tightly packed the particles are in something
density
When heat is added to a solid, it becomes this state of matter
liquid
A state change (melting, freezing, evaporating, etc) is this type of change
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.
heterogeneous
When you leave your razor in the shower, the blades will rust. What kind of change is this?
Chemical
All matter is made up of these.
atoms/particles
If heat is removed, a liquid will become this state
solid
Provide three examples of physical properties.
color, volume, length, mass, weight brittleness, density, ductility, flexibility, malleability, solubility, specific heat, conductivity, viscosity, hardness
Draw a particle diagram of a compound
Should be at least two different types of atoms bonded together
Koolaid, steel, brass, air, and milk are examples of this.
solution/homogeneous mixture
When I bake a meatloaf, I cook it in the over for a long period of time. What kind of change is this?
When I melt chocolate for a smore, what kind of change is this?
Physical
Solids have __________ shape and __________ volume. (definite/indefinite)
Liquids have __________ shape and __________ volume. (definite/indefinite)
Gases have __________ shape and __________ volume. (definite/indefinite)
indefinite, definite
indefinite, indefinite
The state change when a solid becomes a gas.
What is sublimation?
Provide three signs of a chemical change.
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
uniform and definite/unchanging
Solute-
Solvent-
Solute- carbon dioxide
solvent- Water
What is a precipitate?
A solid formed in a solution
