Document Summary

Solid molecules jiggle a little bit, but stay in a fixed position and have the most amount of interactions. Still contact and interact with one another but are able to move around more freely than solids. Can move completely freely and experience very little to none intramolecular forces. The amount of energy needed to complete a transition of phase = h . The transition can be named after each phase (heat of fusion or heat of vaporization) q= n x h q= heat n= number of moles. When a substance absorbs or releases heat, two things can happen: temperature changes or it will undergo a phase change. Heat capacity = c involves the specific heat and mass. Specific heat is a characteristic of elements q=heat.
