solids, liquids, gases

solids

• particles are closely packed in a lattice (fixed arrangement)

• fixed volume

• vibrates

• cannot be compressed

liquids

• particles are close together in a random arrangement

• particles slide past each other

• cannot be compressed

• takes the shape of the container its in

gases

• particles are spread far apart (arrange randomly)

• can be compressed

• moves really quickly

when temperature increases

or when pressure decreases

volume of a gas increases

when pressure increases

volume of a gas decreases

heating curve

cooling curve

liquid state

between melting and boiling point

solid state

below its melting point

gas state

above its boiling point

sublimation

solid to gas

difference between boiling and evaporating

boiling happens over a specific temperature while evaporation happens over a range of temperatures

kinetic particle theory

describes particles in constant motion
