define matter
anything that takes up space
does the image show solid, liquid, or gas
solid
does the image show solid, liquid, or gas
liquid
does the image show solid, liquid, or gas
gas
list four indicators of chemical change
bubbles (creation of gas), temperature change, color change, production of an odor
list four types of matter
atom/element, molecule/compound, homogeneous mixture, heterogeneous mixture
list four states of matter
solid, liquid, gas, plasma
list properties of solids
particles do not move much, definite shape(doesn't change), not much empty space
list properties of liquid
particles slide around, not much empty space, takes on the shape of its container
list properties of gas
particles move a lot, a lot of empty space, very compressible, takes on the shape of its container
list properties of plasma
adds heat to a gas, releases electrons, charged atoms
new substance means
different molecules present
define physical property
observation of a substance without changing it
list examples of physical property
smell, color, density, texture, boiling point, melting point
define physical change
no new substance made, same molecules present before and after, easily reversable
list examples of physical change
change of state, change of shape, change of size, making kool aid
define chemical property
ability of a substance to have a reaction
list examples of chemical property
ability for paper to burn in air, ability for iron to rust
define chemical change
a new substance is made, different molecules present after the reaction
list examples of chemical change
bubbles, heat released, burning, cooking,
define pure substances
has a set composition, same globally, cannot be broken down by physical changes
define atoms
smallest particles
define compounds/molecules
made of two or more atoms (ex: H2O)
define mixtures
has several pure substances mixed together, can be broken down by physical changes
what are the two types of mixtures
homogeneous mixture, heterogeneous mixture
define homogeneous mixture
consistent composition (ex: milk, lotion, salt water)
define heterogeneous mixture
irregular composition (ex: chocolate chip cookies, salad, granite)
what type of particle is this
element
what type of particle is this
compound
what type of particle is this
homogeneous mixture
what type of particle is this
heterogeneous mixture
