Atmosphere. A nuclear hypothesis of Daltona

Since Daltona the nuclear hypothesis makes base of all science. Leaning against it, we build the representations and we measure properties of atoms with the accuracy, which Dalton could not and imagine. We even ' rummage ' in atoms and we find out unforeseen complexity of their components. Daltona some of sights were incorrect: for example, not all atoms of the same element in accuracy are identical. But he the first has understood, how atomisticheskuju the concept which was not perceived seriously during two thousand of years, it is possible to force to live in minds of people and to make a basis for the measurements, capable to set a science further away. Thus, atmosphere studying has led to one of the most important steps to the physicist - to the basis of the quantitative nuclear theory.

In 1801 Dalton, apparently, has made for the first time satisfactory measurements; the measurements executed by another researchers were inexact because of presence of steams of water. It took some gases - oxygen, hydrogen, nitrogen and carbonic gas - and, carefully having dried up them, has placed in the soldered tubes with divisions, and then has locked a mercury drop. Tubes heated up water which was passed between them and special, surrounding them, a shirt. To the surprise, Dalton has found out that all gases behaved equally.

It has formulated the received results in extremely cautious form: ' in general I do not see the sufficient reason, stirring to us to conclude that all ' elastic ' gases at the same pressure equally extend at heating '. However Dalton considered that ability to extend decreases in process of rise in temperature.
