pure substances and mixtures
dependent variable
something you measure or observe in the experament
solute
it is known as solvent
is a substance dissolved in another substance
is a mixture
independent variables
this will usually affect the dependent variables
some thing you can change or manipulate in the experiment
particale
there are spaces between particles
particles of one substance are identical to each other
Particles have forces of attraction between them
temperature will affect the speed at which the Particles move
the particles of matter are in constant motion
pure substances
made up of only one type of particle
constant composition of substances
mixtures
made up of more
then one substance
with different particles
variable amount of substances
mechanical mixture
A heterogeneous mixture
of particles or masses distinguishable
as such under the microscope or separable by filtration.
Saurated
soaked, impregnated, or imbued thoroughly; charged thoroughly or completely; brought to a state of saturation.
solution
s a homogeneous mixture composed of two or more substances
concentraited
Heterogeneous
a process involving substances in different phases (solid, liquid, or gaseous).
homogeneous
is a term in physical chemestry and materials science that refers to substances and which are in a single phase.
science safety
no running
clean area
tie long hair back
wash hands
follow instructions
gloves
pay attention
keep long sleeves
solubility
a chemical property referring to the ability for a given substance,
solvent
is commonly the major fraction of the mixture.
variable
can exist in differing amounts or types.
condition
trait
factor
the particle theory of matter
all matteri s made up of extremely tiny particles
each pure substance has its own kind of
particle
dilute
"bleach can be diluted with cold water"
make (a liquid) thinner or weaker by adding water or another solvent to it.
concentrated
is a homogeneous mixture composed of two or more substances.
(of a substance or solution) present in a high proportion relative to other substances; having had water or other diluting agent removed or reduced
dissolve
"glucose dissolves easily in water"
(with reference to a solid) become or cause to become incorporated into a liquid so as to form a solution.
matter
has mass and occupies volume
made up of particles
Subtopic
Unsaturated
In organic chemistry, a saturated compound is a chemical compound that has a chain of carbon atoms linked together by single bonds.
Controled variable
It's a variable that cannot be changed
A test in which the independent variable
is kept constant in order to
measure changes in the dependent variable
