Guide
Matter - answer anything that has mass and takes up space. can change from one state
to another through heating, cooling, or a change in pressure.
substance - answer a type of matter that cannot be separated out into new material
through a physical reaction
elements - answer substances that cannot be broken down by either physical or
chemical reactions
atoms - answer the building blocks of all elements
mass - answerthe measure of how much of a substance exists in an object
physical properties - answer refers to appearance, mass, temperature, state, size, or
color
chemical properties - answerrefers to the chemical makeup of an object or fluid; change
in alteration in the makeup of an object and forms a new solution/compound
different states of matter - answermelting: solid to liquid
sublimation: solid to gas
evaporation: liquid to gas
freezing: liquid to solid
condensation: gas to liquid
reversible change - answera physical change, changing of the size or shape of an
object without altering its chemical makeup
non-reversible change - answera chemical change, when one or more types of matter
change and results in the production of new materials
mixture - answertwo or more materials are combined
solution - answercannot easily be separated back into its original components
force - answerthe outside influence on an object
measurement of an objects movement - answervelocity= Δx/Δt
