Changes of State
◍ When matter transforms from one state to another
◍ Caused by adding or removing kinetic energy◌ Changes the temperature (average kinetic
energy of particles) ◍ Raise temperature à more kinetic energy à
particles move faster & take up more space◍ Lower temperature à less kinetic energy à
particles move slower & take up less space

Diffusion
◍ Movement of one material through another◍ Particles in motion move from high
concentration to low concentration◍ Ex: why you can smell cookies baking in a
different room

Thermal Expansion & Contraction
◍ Thermal Expansion – When Temperature Increases◌ Energy is added◌ Particles speed increases◌ Particles move farther apart◌ Particles occupy a larger volume

Thermal Expansion & Contraction
◍ Thermal Contraction – When Temperature Decreases◌ Energy is removed◌ Particles speed decreases◌ Particles move closer together◌ Particles occupy a smaller volume
