...assumption that heat is a material substance. Davy said — " The immediate cause of the phenomenon of heat is motion, and the laws of its communication are precisely the same as the communication of the laws of motion." Maxwell, in his Theory of Heat, p. 306, says — " The molecules...

...stated plainly and precisely the real nature of heat, saying: " The immediate cause of the phenomenon of heat, then, is motion, and the laws of its communication...same as the laws of the communication of motion." The basis of this opinion was the same that had previously been noted by Rum ford. So much having been...

...he made the following most important statement : — " The immediate cause of the phenomenon of heat is motion, and the laws of its communication are precisely...same as the laws of the communication of motion." Moreover, the statement that " heat is kinetic energy " is supported by the following considerations...

...on their different quantities of repulsion and attraction." " The immediate cause of the phenomenon of heat, then, is motion ; and the laws of its communication...same as the laws of the communication of motion." He considers this repulsive motion to be analogous to the orbital motions of planets : and that, consequently,...

...in the kinetic or in the potential form? Davy said in 1812 : " The immediate cause of the phenomenon of heat, then, is motion, and the laws of its - communication...same as the laws of the communication of motion." This in modern language is equivalent to the statement that heat is kinetic energy ; not evidently...

...not until 1812 that he came to the conclusion that ' the immediate cause of the phenomenon of heat is motion, and the laws of its communication are precisely...same as the laws of the communication of motion.' From data given by Ktimford, it may be calculated that 940 footpounds of work are necessary to produce...

...separate them.- Again, in 1812, Davy thus states his theory : — i The immediate cause of the phenomenon of heat, then, is motion, and the laws of its communication...precisely the same as the laws of the communication of motion.Another way of stating the above is that heat is a form of energv. To make this point clear...

...was not until 1812 that he distinctly laid down1 that " The immediate cause of the phenomena of heat is motion, and the laws of its communication are precisely...same as the laws of the communication of motion." Both Rumford and Davy might, however, have been successfully Position met by any calorist who was willing...

Heat and mechanical force therefore are identical and convertible. Independently of the medium through...
