Explanation:
According to Newton, compression and rarefaction are created as sound waves spread in air. He thought the process was very slow and the heat produced during compression was given to the surrounding area and heat loss obtained from the surrounding area during compression.
As per Newton's formula -
PV = constant where, P is pressure and V is the volume of air
Newtons equation for sound velocity in gas states that in the process of rarefaction and compression, sound travels. So Laplace corrected it with his hypothesis that during the transmission of sound in gas the mechanism of heat transfer is an adiabatic process which means that heat does not enter or leave the system in question.
