...the boiling-point by the heat resulting from the friction. In this manner it was found that the heat required to raise the temperature of a pound of water, 1° F., is equivalent to 1034 times the force expended in raising a pound weight one foot high, or to 1034...

...and mechanical power generated by the electric current, Mr. Joule was led to conclude that the heat required to raise the temperature of a pound of water 1° F., is equivalent to 838 foot-pounds ; and a nearly equal result was afterwards obtained by experiments...

...with this simple apparatus, Joule deduced as the dynamical equivalent of heat (that is, of the heat required to raise the temperature of a pound of water 1° F.) 770 foot-pounds, 1 differing by only about a quarter per cent. from the results of his subsequent and...

...given temperature to another, a body always liberates exactly the same amount of energy. The amount of energy required to raise the temperature of a pound of water 1°, and to effect its corresponding expansion, is equal to that possessed by a one-pound weight striking...
