AP Chemistry Exam with Verified
Answers
mass - ✔✔the amount of matter in an object
volume - ✔✔the amount of space occupied by an object
extensive property - ✔✔a property that depends on the amount of matter in a sample
intensive property - ✔✔a property that depends on the type of matter in a sample, not the
amount of matter
substance - ✔✔Matter that has a uniform and definite composition
physical property - ✔✔a quality or condition of a substance that can be observed or measured
without changing the substance's composition
solid - ✔✔of definite shape and volume
liquid - ✔✔a substance in the fluid state of matter having no fixed shape but a fixed volume
gas - ✔✔the state of matter distinguished from the solid and liquid states by: relatively low
density and viscosity
vapor - ✔✔matter that exists in the gas state but is generally a liquid or solid at room
temperature
, Physical change - ✔✔a change from one state (solid or liquid or gas) to another without a
change in chemical composition
mixtures - ✔✔a physical combination of substances that can still be seperated
heterogeneous mixture - ✔✔a mixture in which the composition is not uniform throughout
homogeneous mixture - ✔✔a mixture in which the composition is uniform throughout
solution - ✔✔a homogeneous mixture of two or more substances
phase - ✔✔(physical chemistry) a distinct state of matter in a system
filtration - ✔✔the process that separates a solid from the liquid in a heterogeneous mixture
distillation - ✔✔the process of purifying a liquid by boiling it and condensing its vapors
element - ✔✔any of the more than 100 known substances (of which 92 occur naturally) that
cannot be separated into simpler substances and that singly or in combination constitute all
matter
compound - ✔✔a substance made up of atoms of two or more different elements joined by
chemical bonds
chemical change - ✔✔a change that produces matter with a different composition than the
original matter
chemical symbol - ✔✔a one or two letter representation of an element
