...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...

...except it be MOTION." : According to Joule's reduction of these result«, they indicate that the heat required to raise the temperature of a pound of water one degree Fahr., is equivalent to the mechanical energy represented by 1034 foot-pounds. This number differs...

...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...

...density of water, which is 39. 1 degrees Fahrenheit. The variation in the quantity of heat neceasary to raise the temperature of a pound of water one degree is so slight for any temperature between 32° and 212°, that in general the British thermal unit may...

...thai 1390 units of work are equivalent to one unit of heat (centigrade). A unit of heat is the heat required to raise the temperature of a pound of water one degree. A unit of work is the work performed in raising a pound weight one foot high. MECHANICAL POWERS—...

...water the same number of degrees, is called the specific heat of the substance. The quantity of heat required to raise the temperature of a pound of water one degree Centigrade, may be conveniently adopted as the thermal unit. We then speak of the specific heat of...

...contains. Thus the thermometer does not lead us to suspect that about thirty times the quantity of heat is required to raise the temperature of a pound of water one degree as would suffice to raise the temperature of a pound of mercury one degree; yet such is the fact, as...

...see page 95. B. FEED- WATER HEATERS, Gain from the use of. — A unit of heat is the amount of heat required to raise the temperature of a pound of water one degree, the water being at the temperature of maximum density, about 39.1° Fahrenheit. The table below shows...
