...between the heat 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...

...1864.) 6th. That the Specific Heat of iron is 0-113795, that of water being unity. In other words, that the heat required to raise the temperature of a pound of water one degree, will raise the temperature of a pound of iron 8'8°. (Ibid.) 7th. That the velocity of a freely-falling...

...raised to a height of seven hundred and seventy -two feet, a quantity of heat is consumed, suffieient to raise the temperature of a pound of water one degree Fahr. Consequently, on climbing to a height of fifteen thousaud seven hundred and seventy-four feet, or about...

...between the heat 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; this he afterwards reduced to 772 ; and a nearly equal result...

...was raised to the boilingfrf'int 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 by 1° F. is equivalent to 1034 times the force expended in raising a pound weight one foot high, or...

...and other forms of force ; — the general fact being stated in this form, that the amount of heat required to raise the temperature of a pound of water one degree Fahrenheit will generate force enough to raise seven hundred and seventy-two pounds one foot. This...
