Question: Sound waves propagate through a media as pressure waves that cause the media to go through isentropic compression and expansion processes. The speed of sound

Sound waves propagate through a media as pressure waves that cause the media to go through isentropic compression and expansion processes. The speed of sound c is defined by c2 = (∂P/∂ρ)s and it can be related to the adiabatic compressibility, which for liquid ethanol at 20°C is 9.4 × 10-10 m2/N. Find the speed of sound at this temperature.
