Down: 1) move slower and contract5) T celcius+2737) physical changes (from solid, liquid to gas). Requires energy to overcome intermolecular forces.8) the amount of space that a material takes up9) Processed release energy as they happen. Changing to a solid slows molecules down releasing energy14) point where all three phases exist at the same time.
