...applied in the condensation of the air capable of raising 795 Ibs. to the height of one foot in order to raise the temperature of a pound of water one degree of Fahrenheit's scale. In another experiment, when the air condensed in one vessel was allowed to pass... | |

...explained the meaning of this great governing principle stands Joule, the worthy successor of Dalton. ' Mr. Joule has proved that the quantity of heat requisite...expended in percussion, friction, or raising a weight, n. definite quantity of heat is generated ; and conversely, when work is performed by the consumption... | |

...found that one pound of matter, falling seven hundred and seventy-two feet, will produce heat enough to raise the temperature of a pound of water one degree of Fahrenheit. This is now received as the unit of force. 5. Force is indestructible. It is never increased... | |

...Helmholtz, Him, Eegnault, &c., establish that a calorie is equivalent to 425 kilogrammeters, that is to say that the quantity of heat requisite to raise the temperature of a kilogram of water to 1 degree centigrade produces a mechanical action represented by the elevation... | |

...same ratio that it does up to that temperature, it would be about 0'26 at 1650°, so that in this case the quantity of heat requisite to raise the temperature of a pound of iron to that extent above 16° — the average atmospheric temperature — would be 424'84 heat unite.... | |
