The kinetic particle theory explains the properties of solids, liquids and gases. There are energy changes when changes in state occur. Brownian motion is the random movement of fluid particles.

What shape are changes of state in a heating curve?
How is evaporation different from boiling?
How is the arrangement of particles in a solid different from those in a gas?
