It state that ', The compressions and rarefactions are always used for transmitting sound. Propagation was thought to be a slow process. Newton postulated that heat was produced during propagation. During rarefactions, the heat that is emitted into the environment during compressions is recovered. Hence propagation of sound is based on isothermal process. i.e PV=Constant
