Matter, Mass, Volume, and Density- Science
density
a measurement of how tightly packed particles are. you measure density by finding an objects mass and volume, then dividing the two.
the formula for volume
length times width times height
formula for density
mass divided by volume
characteristics of liquid
particles less tightly packed, no definite shape but definite volume, particles have medium energy, move past each other
characteristics of gas
particles move freely and widely, they have no definite shape and no definite volume, they move very quickly, have a large amount of energy
characteristics of solid
particles tightly packed together, definite shape and volume, particles vibrate and have small amount of energy
mass
the amount of matter or "stuff" an object is made out of. you use a triple beam balance to measure mass.
volume
the amount of space matter takes up. you use a graduated cylinder to measure volume.
weight
the measure of the pull of gravity on an object. you can use a scale to measure weight.
three major states of matter
the three major states of matter are solid, liquid, and gas
