TermDefinition
atom Smallest particle of an element that has the properties of that element
molecule the particle of a kind of compound (ex.: H2O)
element Substance with a single kind of atom; ex. O2 (oxygen)
property Describes a substance or object
closed system Nothing gets in or out -- like a closed box or balanced equation.
conservation of matter Stuff doesn't go away, and it doesn't come from nowhere.
physical change A change in some description (property) for a substance, but it remains the same substance
density The amount of matter in a given volume: D=m/v
temperature A measurement of the average thermal energy (commonly called "heat") in a substance
mixture Two or more substances combined (Do not confuse with compound.)
compound A particle (molecule or ionic) made of two or more elements (Do not confuse with mixture.)
volume Measures how much space the object takes up, given in cubic units or liters
chemical change When a substance becomes new substance(s) with new properties
matter Anything that has volume and mass
characteristic property Description for a substance that could identify the substance, no matter how much you had
substance Matter of all one kind of particle, and with specific properties
mass A measurement of the amount of matter in an item; does not change with gravity
weight A measure of the force of gravity on an item; do not confuse with mass
heat a transfer of thermal energy from a warmer object to cooler one (and ALWAYS in that direction)
solid particles close together, vibrating in place; may be formed from molecules or crystals
liquid particles close together like solid but can change relative position
gas particles widely spaced and moving freely
endothermic reaction in which products store energy in chemical bonds from surroundings, having more stored energy than the reactants; detected as decrease in temperature
exothermic reaction in which products release energy from chemical bonds to surroundings, having less stored energy than the reactants; detected as increase in temperature
reactants the starting substances in a chemical change
products (chemical change) the resulting substances from a chemical change
