Topic 3 - Particle model of matter ( 1. density and states of matter ) Flashcards
what is density
measure of compactness of a substance. relates to the mass and how much space it takes up.
formula for density
p = m/v
what are the 3 states of matter
solid liquid gas
describe the arrangement of particles in a solid
In a solid, particles are packed tightly together in a regular pattern. Solids have fixed shaped that are hard to break apart because individual particles do not have enough energy to escape individually. Solids are ALWAYS in a regular lattice pattern
describe the arrangement of particles in a liquid
In liquids, the particles are near each other, but not tightly packed. The particles in a liquid are able to slide past each other. … The looser arrangement of particles is what allows liquids to take on the shape of their container.
describe the arrangement of particles in a gas
gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern
