Відповідь:

За молекулярно-кінетичної теорії, всі речовини утворені з найдрібніших частинок — молекул і ці частинки взаємодіють одна з одною силами, що мають електричну природу. Коли дим вогнища піднімається частинки, молекули диму взаємодіють з частинками, молекулами повітря і відбувається дифузія. Дифузією називається явище проникнення двох або кількох дотичних речовин одна в одну. Дифузія призводить до утворення однорідної суміші, незалежно від густини компонентів.

The British believe it’s their duty to make men of their children, to make them hard and tough.
No other country has created such harsh institutions as British boarding schools where they keep their children from the age of eight to eighteen.
A boy’s first week at his preparatory school is likely to be the most traumatic experience of his life. Until that moment, he has not realized that there are so many people in the world who wish to hit him and to hurt him and that they will be given every opportunity to do so, both by day and by night.
In no state school or prison would a boy be given 17 strokes of the cane for misbehaviour. But in public schools these measures have been approved, partly because they keep discipline effectively, partly because they teach senior boys responsibility and a sense of authority, and particularly because a good beating is supposed to be good for boys, whether deserved or not.
Cold also plays an important role in the training of a British child. British dormitories are unheated. At Gordonstown School in the north of Scotland the boys wear shorts and take cold showers even in winter. At night, all windows are opened, and no boy is allowed more than two blankets. This is a matter not of neglect, but of deliberate policy: cold, hard conditions are thought to produce tough, reliable leaders.
Another major tradition of upbringing is the discipline of hunger. British children are sometimes too hungry to learn, too hungry to concentrate on lessons. Various reasons are given for this phenomenon of hungry children. But behind them all is the deep British feeling that a plump child is a spoiled child and a matter of shame and that a lean child is healthy, tough and likely to make his mark in the world later on.
Those at day schools, living at home, have an earlier time, and the schools, seeing their pupils for only a few hours a day, concentrate more on work than on character training. But the idea that boarding school is the ideal form of education is winning wider recognition, and more and more middle-class parents are coming to feel it’s their duty to find the money somehow to send their children to boarding school.
The object of a public school education is not to learn anything useful or indeed to learn anything at all. It is to have the character and mind trained, to have the right image, and to make the right friends.
