...the combined engines require no power to work them— a result which is absurd, since it may be foken as an axiom that — Heat cannot be made to pass from a cold body to a hot one without the expet1diture of work. Deductions : (1.) By supposing E' also reversible, we may invert the above reasoning,... | |

...of any external agency. By the employment of mechanical energy drawn from external bodies, heat may be made to pass from a cold body to a hot one, the amount of energy required being greater the greater the difference of temperature. And the method... | |

...significance of the second law becomes at once apparent. It is conceivable, of course, that heat may be made to pass from a cold body to a hot one, just as we may pump water from a lower to a higher level. Thus, in the operation of the ammonia refrigerating... | |

... heat, or of causing other bodies to yield it, and in order that a heat engine may function, it must have two sources, one hot and the other cold. From this statement it is seen even more directly perhaps than from that of Duhem that this principle...
