...a certain experiment performed by Joule, who announced in the Philosophical Magazine for May, 1845, that "no change of temperature occurs when air is...such a manner as not to develop mechanical power." Although the interpretation thus put upon Joule's words seems to be perfectly natural and legitimate,... | |

...temperature took place. The inference from this is that no appreciable change of temperature takes place when air is allowed to expand in such a manner as not to do any work. It was formerly supposed that air by its mere expansion became colder, and by its mere... | |

...[3J, May 1845, and i Collected Papers,' vol. ip 182), is not rigidly correct : this proposition stated that " no change of temperature occurs when air is...such a manner as not to develop mechanical power." The merit of Joule's discovery is not in any way diminished by this. He himself showed experimentally... | |
