Page 41 - It is hardly necessary to add, that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance ; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner the Heat was excited and communicated in these experiments, except it be MOTION.
Page 235 - A definite quantity of heat is required to raise the temperature of a given mass of any material by 1 (degree).
Page 43 - The immediate cause of the phenomena of heat then is motion, and the laws of its communication are precisely the same, as the laws of the communication of motion.
Page 42 - I procured two parallelopipedons of ice, of the temperature of 29°, six inches long, two wide, and two-thirds of an inch thick: they were fastened by wires to two bars of iron. By a peculiar mechanism, their surfaces were placed in contact, and kept in a continued and violent friction for some minutes. They were almost entirely converted into water, which water was collected, and its temperature ascertained to be 35°, after remaining in an atmosphere of a lower temperature for some minutes. The...
Page 34 - I think we may safely conclude, that ALL ATTEMPTS TO DISCOVER ANY EFFECT OF HEAT UPON THE APPARENT WEIGHTS OF BODIES WILL BE FRUITLESS.
Page 239 - The ordinary specific heat of a substance has been defined as the quantity of heat required to increase the temperature of unit mass of the substance 1° C., under given conditions.
Page 40 - But without insisting on the improbability of this supposition, we have only to recollect, that from the results of actual and decisive experiments, made for the express purpose of ascertaining that fact, the capacity for Heat of the metal of which great guns are cast is not sensibly changed by being reduced to the form of metallic chips in the operation of boring cannon...
Page 88 - Mayer appears to have hastened to publish his views for the express purpose of securing priority. He did not wait until he had the opportunity of supporting them by facts. My course, on the contrary, was to publish only such theories as I had established by experiments calculated to commend them to the scientific public, being well convinced of the truth of Sir J.
Page 22 - Thermal unit, is the quantity of heat necessary to raise the temperature of one pound of water, one degree, or from 39° to 4o° Fah.
Page 105 - The two fixed points that are ordinarily chosen for a thermometer are the melting point of ice and the boiling point of water. The...
