...published. In fact, in 1812 he enounces this proposition : — ' 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.' Now, we see at a glance to what an immense extent the science had been advanced in Davy's time. When... | |

...outward disturbance. And in 1812, Davy announced the axiom. " 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." But all the while, as late as 1840, these ideas were laughed at as extravagancies, when it was made... | |

...Hence Davy* drew the conclusion that "the immediate cause of the phenomena of heat is motion, and t lie laws of its communication are precisely the same as the laws of the communication of motion." The mechanical, or dynamical theory, which regarded heat as consisting in a state of molecular motion,... | |

...35°; and he announced the important proposition, 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." Our more extended knowledge enables us to confirm the views expressed by Davy. now accepted as 772... | |

...motion." Davy defines heat as "a peculiar motion," and in his " Chemical Philosophy" tells us that " the laws of its communication are precisely the same as the laws of the communication of motion." Locke, later on,* insists that " what in our sensation is heat, in the object is nothing but motion."... | |

The basis of this opinion was the same that had previously been noted by Rumford. So much having been... | |

...separate them.' Again, in 1812, Davy thus states his theory : — ' 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.' Another way of stating the above is that heat is a form of energy. To make this point clear before... | |
