Is it true that Pierre-Simon Laplace corrected Isaac Newton's calculation of the speed of sound by identifying that the process is adiabatic rather than isothermal?
Yes. Multiple reliable and scholarly sources confirm that Pierre-Simon Laplace corrected Isaac Newton's calculation of the speed of sound by recognizing that sound wave compression is adiabatic rather than isothermal.
