...method of calculation it is assumed that a body radiates heat, ie, falls in temperature, at a rate which is proportional to the difference between its temperature and that of the surrounding atmosphere. This is a law of cooling which was announced by Newton, — a law which is not even approximately... | |

...whose temperature is kept fixed and which is cooler than the body, the latter will cool off at a rate proportional to the difference between its temperature and that of the surrounding medium. This law of cooling, due to NEWTON, may be expressed by the formula where 00 is the temperature of... | |
