I want to know why we can treat sound waves as an adiabatic process. Preciseley, I know that pressure and density vibrations occur so fast that molecules have no time to exchange energy (I might be wrong). But I would like a deeper explanation, not using a mathematical argument, but maybe a physical and numerical one (I haven't found any useful data to help me argument this fact).
