kinetic energy

gas

the particles move far apart to all areas of the container filling it completely

liquid

the particles slide over and around each other

solid

the particles vibrate and wiggle in one place

pure substances and mixtures

Controled variable

A test in which the independent variable is kept constant in order to measure changes in the dependent variable

It's a variable that cannot be changed

Unsaturated

In organic chemistry, a saturated compound is a chemical compound that has a chain of carbon atoms linked together by single bonds.

matter

Subtopic

made up of particles

has mass and occupies volume

dissolve

(with reference to a solid) become or cause to become incorporated into a liquid so as to form a solution.

"glucose dissolves easily in water"

concentrated

(of a substance or solution) present in a high proportion relative to other substances; having had water or other diluting agent removed or reduced

is a homogeneous mixture composed of two or more substances.

dilute

make (a liquid) thinner or weaker by adding water or another solvent to it.

"bleach can be diluted with cold water"

the particle theory of matter

each pure substance has its own kind of particle

all matteri s made up of extremely tiny particles

variable

factor

trait

condition

can exist in differing amounts or types.

solvent

is commonly the major fraction of the mixture.

solubility

a chemical property referring to the ability for a given substance,

science safety

keep long sleeves

pay attention

gloves

follow instructions

wash hands

tie long hair back

clean area

no running

homogeneous

is a term in physical chemestry and materials science that refers to substances and which are in a single phase.

Heterogeneous

a process involving substances in different phases (solid, liquid, or gaseous).

concentraited

solution

s a homogeneous mixture composed of two or more substances

Saurated

soaked, impregnated, or imbued thoroughly; charged thoroughly or completely; brought to a state of saturation.

mechanical mixture

A heterogeneous mixture of particles or masses distinguishable as such under the microscope or separable by filtration.

mixtures

variable amount of substances

made up of more then one substance with different particles

pure substances

constant composition of substances

made up of only one type of particle

particale

the particles of matter are in constant motion

temperature will affect the speed at which the Particles move

Particles have forces of attraction between them

particles of one substance are identical to each other

there are spaces between particles

independent variables

some thing you can change or manipulate in the experiment

this will usually affect the dependent variables

solute

is a mixture

is a substance dissolved in another substance

it is known as solvent

dependent variable

something you measure or observe in the experament
