|
|
|
anything that has mass and occupies space
|
matter
|
MMMMMMMater has MMMMMMMMMasss and it occupies space
|
|
|
a substance that cannot be broken down into simpler substances
|
element
|
the element brand cant be broken into other little brands because its already a brand on its own
|
|
|
the smallest particle that has the properties of an element
|
atom
|
atom is very little because a looks tiny for some reason
|
|
|
a substance made of atoms of more than one element bound together
|
compound
|
when you compound stuff together you put them together
|
|
|
the smallest unit of a substance that exhibits all of the properties characteristic of that substance
|
molecule
|
a mole is usually very small..the smallest
|
|
|
the chemical symbols and numbers indicating the atoms contained in the basic unit of a substance
|
chemical formula
|
when you see numbers and symbols think of a formula in math then put it together with science and figure out that its chemical formula
|
|
|
any matter that has a fixed composition and definite properties
|
pure substance
|
when someone looks good and is pure they usually has a fixed look with their hair and clothes and definite style instead of changing it everyday
|
|
|
a combination of more than one pure substance
|
mixture
|
whens theirs a combination another word for it is called mixture..self explanitory if u jus read the question
|
|

|
miscible
|
in MI(mission impossible) two people were able to go into eachother like tom cruis and his gf havin sex
|
|
|
describes two or more liquids that do not mix into eachother
|
immiscble
|
IM means not, and i should i already know what missible means
|
|
|
the change of a substance from a liquid to a gas
|
evaporation
|
we learned it back in like 4th grade with miss tochi
|
|
|
the change of a substance from a gas to a liquid
|
condensaton
|
the opposite of evaporation
|
|
|
the change of a substance from a solid to a gas
|
sumblimation
|
|
|
|
the way a substance reacts with others to form new substances with different properties
|
chemical property
|
|
|
|
the ability of a substance to combine chemically with another substance
|
reactivity
|
when something is reactive it usually combines with eachother
|
|
|
a characteristic of a substance that can be observed or measured without changing the composition of the substance
|
physical property
|
when you see the word characteristic think of physical property
|
|
|
the temperature at which a solid becomes a liquid
|
melting point
|
self explanitory
|
|
|
the temperature at which a liquid becomes a gas below the surface
|
boiling point
|
stuff boils underground
|
|
|
the mass per unit volume of a substance
|
density
|
mass= density so when you see the word mass think of destiny
|
|
|
the force with which a more dense fluid pushes a less dense substance upward
|
buoyancy
|
when you bounce someone on a trampoline usually the more dense person "launches" the smaller person higher and upward..so bouyancy is the "trampoline" theory
|
|
|
a change that occurs when a substance changes composition by forming one or more new substances
|
chemical change
|
when you see the term "when a substance changes" then think of chemical change
|
|
|
a change in the physical form or properties of a substance that occurs without a change in composition
|
physical change
|
it says physical in the definition so just match it with the answer
