 ... boils at 212°. The heat of the air in Great Britain varies from below 32° in the winter, up to 80° or 90° in the summer. "Whether exposed to one temperature or another, the heat of the body is always 98°, thus showing that its heat depends on...

...is, by the warmth of the season ; and leaves and fruit are in due time produced. Or, in other words, the chemical combination of the oxygen of the air with the carbon and other of the elements of the seed or sap of the tree takes place ; and this is attended with an evolution... | |

...98°, thus showing that its heat depends on internal sources. This heat is produced by the contact of the oxygen of the air with the carbon and hydrogen contained in the tissues and the blood. The food containing carbon and hydrogen is brought in contact with the oxygen... | |

...blow on the face excites a flash of light. Nervous excitement, by accelerating respiration, increases the chemical combination of the oxygen of the air with the carbon of the blood, and thus produces animal heat. But the development of electricity by nervous and muscular... | |

...which will afterward be continued by the oxygen of the air. Ordinary combustion is due to the union of the oxygen of the air with the carbon and hydrogen contained in the coals, oils, fats, and gases of our fires and flames. The rusting of iron, the decay of wood, the process... | |

...How is the heat of your own body produced ? The heat of a fire is produced by combustion, that is, by the chemical combination of the oxygen of the air with the carbon of the fuel. Ordinary coal consists mainly of carbon and hydrogen ; when it is lighted the oxygen of... | |
