Why is the change in the air, as a sound wave passes, adiabatic and not isothermal?
The pressure of the air does not change as the sound passes
Air is a good conductor of heat, so the temperature stays fixed
Sound waves carry no energy, so no heat can flow
The compressions and rarefactions are too quick for heat to flow in or out

← In methane gas at a pressure of 1.20 × 10⁵ Pa the density is 0.78 kg/m³, and γ = 1.31. What is the speed of sound in it?
Sound travels at a certain speed in air at -23 °C. At what temperature is it 1.5 times as fast? →
