Heat

A. Privat Deschanel - 1874
...Now the ratio THERMIC ENGINES. 453 of 83-66 to 59-3 is 1-41, which, as we have already seen (§ 347), is the ratio of specific heat at constant pressure to specific heat at constant volume. In the case of air and perfect gases, the heat gained by compression or lost in expansion is almost...
