...begins to boil briskly. In a vacuum water may be made to boil by the heat of the hand. For a similar reason, water boils at a lower temperature on the top of a mountain than at its foot, being pressed upon by a less column of air in the former case. For every 430 feet we ascend,... | |

...Whatever may be its cause, the effect of pressure is to raise the boiling point. It is well known that water boils at a lower temperature on the top of a mountain than at its base. It does so because the pressure of the air upon it is less. This very important principle may be easily... | |

In a vacuum, boiling commences at a much lower temperature than in the air. This is shown by placing some hot water under a receiver and exhausting the air. The pressure of the atmosphere being removed from its surface, the water soon boils ; but it comes...
