...assigned a dynamic value—838 foot-pounds, subsequently corrected to 772 foot-pounds—as that of the quantity of Heat required to raise one pound of water one degree, Fahrenheit, of temperature, supposing the original temperature of the water to be between 55 deg. and...

...temperature of one kilogramme of water, or one gramme, from 0" to 1" C. The English unit of heat is the quantity of heat required to raise one pound of water one Fahrenheit degree between 55° and 60". Others adopt as the thermal unit the quatitity of heat necessary...

...pound in weight one foot hi;/h, at the surface of the earth. Now he proved by his experiment — That the quantity of heat required to raise one pound of water one degree, Fahrenheit, was equivalent, if converted into mechanical force, to raise one pound in weight seven...

...natural unit of heat, relative values alone can be obtained and the nnit assumed may be the amount of heat required to raise one pound of water one degree in temperature. The value of the elements is expressed in terras of this unit, and the value of the coals in this table...

...natural unit of heat, relative values alone can be obtained and the unit assumed may be the amount of heat required to raise one pound of water one degree in temperature. The value of the elements is expressed in terms of this unit, and the value of the coals in this table...

...The temperature of a body is independent of the amount of heat in it. A unit of heat is the amount of heat required to raise one pound of water one degree in temperature; and specific heat is the amount of heat required to raise one pound of a given substance one degree in...

...430 kilogrammetres. Mr. Joule makes the mechanical equivalent of heat 772 foot pounds — that is, the quantity of heat required to raise one pound of water one degree of Fahrenheit is equal to the heat produced by one pound of water falling 772 feet ; and it would raise...

...There are cases in which both of these results are valuable. There being no absolute unit of heat, the heat required to raise one pound of water one degree in temperature (or one kilogram one degree) is usually assumed as the standard. 353. The ultimate analysis (made in...

...produced as its equivalent. Heat is measured in heat-units; that is, the UNIT OF HEAT is that amount of heat required to raise one pound of water one degree in temperature. For physical problems the Centigrade thermometer is universally employed; but with English-speaking...
