...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...
