Sound And Heat

Sound tends to basically be formed by the harmonic vibration of molecules, whereas heat tends to basically be formed by the anharmonic vibration of molecules.  Therefore -- the nature of the formation of sound, is more affiliated with the activity of a tense of Wess-Zumino interactions; whereas -- the nature of the formation of heat, is more affliated with the activity of a tense of Cevita interactions.
