The study of the composition of matter and the changes that matter undergoes
Anything that has mass and takes up space
The amount of matter an object contains
Matter with a uniform and definite composition, all have identical physical properties
Quality or condition that can be observed or measured without changing the substance's composition. (color, solubility, density, melting point, boiling point, physical state).
Intensive Physical Property
Does not depend on the amount of matter present (e.g color, melting point).
Extensive Physical property
Does depend on amount of matter present
the condition of matter existing as a solid, liquid, or gas
the gaseous state of a substance that is generally a liquid or solid at room temperature.
Alters a given material without changing its composition.
A physical blend of two or more substances. Can be separated by physical means. Composition may vary.
Not uniform in composition
completely uniform composition (A.K.A a solution)
Substance or Mixture
two things a substance can be
A substance that cannot be broken down into simpler substances. They are the simplest forms of matter, Building blocks for all other substances, and represented by a one or two letter chemical symbol.
compounds can be separated by....
when one or more substances change into new substances
starting substances in a chemical reaction
resulting substance in a chemical reaction
The ability of a substance to undergo chemical reactions and to form new substances
Result in a change of chemical composition of the substances involved.
Law of Conservation of Mass
In any physical change or chemical reaction, mass is neither created nor destroyed. The mass of the products is always equal to the mass of the reactants.
mass per unit volume
process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated
a reaction in which an elementary substance displaces and sets free a constituent element from a compound
derived from experiment and observation rather than theory
the curve at a liquid's surface by which one measures the volume of the liquid
capable of mixing
not capable of being mixed into stable solutions
counterweight consisting of an empty container that is used as a counterbalance to obtain net weight
A liquid's resistance to flowing
