From data given by Ktimford, it may be calculated that 940 footpounds of work are necessary to produce...

...corpuscles of bodies tending to separate them.- Again, in 1812, Davy thus states his theory : — i The immediate cause of the phenomenon of heat, then,...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...

...then, in 1812, for the first time, stated plainly and precisely the real nature of heat, saying : " The immediate cause of the phenomenon of heat, then,...same as the .laws of the communication of motion." Heat and mechanical force therefore are identical and convertible. Independently of the medium through...

Davy said in 1812 : ' The immediate cause of the phenomenon of heat, then,...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...

These essays of Rumford and Davy failed to produce, with a few rare exceptions, any perceptible effect...

The first of these propositions should now be amended in view of the doctrine of the Conservation of...

...scientific men. In 1812, Davy enounced that the direct cause of the phenomenon of heat is motion, and that the laws of its communication are precisely the same as the laws of the communication of motion. The researches into the radiation and absorption of heat mainly form the physical basis of Spectrum...
