Pure Substance
matter that always has exactly the same composition; an element or compound
Element
a substance that can not be broken down into simpler substances
Atom
the smallest particle of an element
Compound
a substance that is made from two or more simpler substances and can be broken down into those simpler substances
Heterogeneous mixture
a type of mixtrue in which the parts of the mixture are noticeably different from one another
Suspension
a heterogeneous mixtrue that seperates into layers over time
Colloid
a mixture that contains some particls that are intermediate in size between the small particles in a solution and the larger particels in a suspension
Physical property
any characteristic of a material that can be observed or measured without changin the composition of the substances in the material
Viscosity
the tendency of a liquid to keep from flowing; restistance to flowing
Conductivity
a material's ability to allow heat or electric charge to flow
Malleability
the ability of a solid to be hammered without shattering
Melting Point
the temperature at which a substance changes froms solid to liquid
Boiling Point
the temperature at which a substance boils; the temperature at which vapor pressure is equal to atmospheric pressure
Filtration
a process that seperates materials based on the size of their particles
Distillation
a process taht seperates the substances in a solution based on their boiling points
Physical change
a change that occurs when some properties of a material change, but the substances in the material stay the same
Chemical Property
any property that produces a change in the composition of matter
Flammability
a material's ability to burn in the presence of oxygen
Reactivity
a property that describes how readily a substance combines chemically with other substances
Chemical Change
change that occures when a substance reacts and forms one or more new substances
Precipitate
a solid that forms and seperates from a liquid mixture
Solid
the state of matter in which materials have a definite shape and a definite volume
Liquid
the state of matter in which material has definite volume but takes the shape of its container
Gas
the state of matter in which material has neither a definite shaper nor a definite volume
Kinetic Energy
the energy an object has due to its motion
Pressure
The result of a force distribued over an area
Absolute Zero
a temperture of 0 Kelvins
Charles's Law
the direct proportion if the volume of a gas to its temperte (in kelvins) if the pressure and the nubmer of particles of the gas are constant
Boyle's Law
the inverse variation of the volume of a gas w/ its pressure if the temperature and the number of particles are constant
Phase Change
a reversible physical change that occurs when a substance changes from one state of matter to another
Endothermic
a description of a change in which a system absorbs energy from its surroundings
Heat of Fusion
the energy of a substance must absorb in order to change from a solid to a liquid
Exothermic
a description of a change in which a system releases energy to its surroundings
Vaporization
the phase change in which a substace change from a liquid into a gas
Heat of Vaporization
the enrgy of a substance must absorb in order to change from a liquid to a gas
Evaporation
the process that changes a substance from a liquid to a gas at temperatures below the substance's boiling point
Vapor Pressure
the pressure caused by the collisions of particles in a vapor w/ the walls of a container
Condensation
the phase change in which a substance changes from a gas or vapor to a liquid
Sublimation
the phase change in which a substance changes from a solid to a gas or vapor w/o changing to a liquid first
Deposition
the phase change in which a gas or vapor changes directly into a solid w/o first change into a liquid
