...proved that by multiplying Newton's velocity by the square root of the ratio of the specific heat bf air at constant pressure, to its specific heat at...volume, the actual or observed velocity is obtained. The mechanical equivalent of heat may be deduced from this ratio ; it is found to be the same as that established... | |

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.... | |

...determined ? In what order do the higher rates of vibration of a tuning fork follow each other ? r. From the ratio of the specific heat of air at constant pressure to its specific heat at constant volume you are required to deduce the mechanical equivalent of heat. How will you do it ? s. Sketch an experimental... | |
