...substance. It now remained to ascertain whether the new gas was an element or a compound. Eamsay determined the ratio of the specific heats of the gas at constant pressure and constant volume, finding T66 as a result. This coincides with the corresponding value for a monatomic gas, such as mercury.... | |

...occurs, it is found that the temperature varies in such a way that //Pr=constant, 1 or poc/A / where 7 is the ratio of the specific heats of the gas at constant pressure and constant volume respectively. From the characteristic equation we easily see that the constant R may be expressed by... | |
