Atom – the smallest, most basic unit of matter. Everything is made up of
atoms.
Chemical Change – A change that occurs when one or more substances
change into entirely new substances.
Closed System – a system that has no input or output (ex: a closed pop
bottle)
Composition – What something is made out of
Compound – A substance made up of atoms of two or more different
elements joined by chemical bonds.
Condensation – Phase change from a gas to a liquid
Density – How “packed together” the atoms in a piece of matter are
Element – a substance that cannot be separated or broken down into
simpler substances. Listed on the Periodic Table.
Evaporation – A phase change from liquid to gas
Freezing – A phase change from liquid to solid
Kinetic Energy – the energy of motion
Mass – The measure of the amount of matter in an object
Matter – anything that has mass and takes up space
Melting – A phase change from solid to liquid
Milliliter (mL) – 1/1000th of a Liter. Unit of liquid volume measurement
Mixture – A combination of two or more substances that are not chemically
combined
Molecule – More than one atom together in a bond (Ex: H2O)
Solubility – The ability of a substance to dissolve in another
State of Matter – the physical forms of matter. Solid, liquid and gas
Sublimation – Phase change where a solid goes directly into a gas
Thermal (Heat) Energy – The energy of heat
Volume – How much space a piece of matter takes up
