...of compression to a like amount will increase the temperature by nearly two-thirds, in consequence of the ratio of the specific heat at constant pressure to that at constant volume being now 1'66. It is not so easy to explain why the bright band should appear while the sodium is... | |

...p/p0=(p/Po)'r comes to rest adiabatically the stop pressure is as shown in hydrodynamics, y=Cp/Cv being the ratio of the specific heat at constant pressure to that at constant volume. This formula is valid for engineering speeds below that of sound in the fluid; for higher and for extremely... | |

...Now in § 80 (equation 80) we saw that under adiabatic conditions the elasticity was yP, where y is the ratio of the specific heat at constant pressure to that at constant volume. The question therefore arises whether in the case of soundwaves in a gas the changes of pressure are... | |
