matter
anything that has mass and takes up space
molecule
smallest piece that matter can be broken into without changing the matter
solid
state of matter in which molecules vibrate, are tightly packed, and have low amounts of energy
liquid
state of matter in which molecules flow over each other, are loosely packed, and have medium amounts of energy
gas
state of matter in which molecules are fast moving, are spaced far apart, and have high amounts of energy
physical property
characteristic of matter that can be observed or measured without changing the matter
mass
measure of the amount of matter in an object
volume
measure of the amount of space matter takes up
sound
energy caused by vibration
density
amount of matter in a given space
conductor
matter that allows heat, electricity, or sound to pass through
insulator
matter that does not allow heat, electricity, or sound to pass through
circuit
electric charges flowing through a closed path
current
continuous flow of charge caused by the motion of electrons
dissolve
make into a solution
solution
mixture that is blended completely and looks the same everywhere
mixture
two or more substances that are combined but can be separated
constant property
property that remains the same regardless of the location of the matter
