...sound in atmospheric air. We found Laplace, by a special assumption, deducing from these velocities **the ratio of the specific heat of air at constant pressure, to its specific heat at constant volume.** We found Mayer calculating from this ratio the mechanical equivalent of heat ; finally, we found Mr.... | |
