1

Why can we not make water hotter when it is boiling?

Почему мы не можем сделать воду горячей, когда она кипятит?

2

When water is boiling, you can make it hotter, but not as a liquid.

Когда вода кипит, вы можете сделать ее горячее, но не как жидкость.

3

We cannot make water hotter than a hundred degrees, because it will turn into water-vapor.

Мы не можем сделать воду более горячей, чем сто градусов, потому что она превратится в воду.

4

But it is quite possible to make water-vapor hotter than the temperature of boiling water. If we go on boiling water, we are putting heat into it.

Но вполне возможно сделать водяной пары горячее, чем температура кипящей воды. Если мы пойдем на кипящую воду, мы вкладываем в нее тепло.

5

We must not think that if the water cannot become hotter, the heat is lost.

Мы не должны думать, что если вода не может стать горячей, тепло теряется.

6

No.

Нет.

7

The heat goes into water, and the water takes the form of a gas, and the heat still remains.

Тепло входит в воду, и вода принимает форму газа, и тепло все еще остается.

8

Though the heat is not making water hotter, it makes the water-vapor hotter. On the other hand, we must always remember that the boiling-point of water depends on air pressure. On the top of a high mountain, where the air pressure is less, the water boils at a lower temperature.

Хотя жара не делает воду горячей, это делает воду горячее. С другой стороны, мы всегда должны помнить, что точка кипения воды зависит от давления воздуха. На вершине высокой горы, где давление воздуха меньше, вода кипит при более низкой температуре.

9

At the Dead Sea, which is more than two thousand feet below sea-level, and where the air pressure is greater, the boiling-point of the water is higher. * * * Why a full bottle keeps heat longer than a bottle which is half full. A bottle full of hot water contains more heat than a bottle which is only half full. Different things take different amounts of heat to be raised to the same temperature. Let us take some water and the same amount of anything else in the world, and make them five degrees hotter than they were before.

В Мертвое море, которое находится более чем в двух тысячах футов ниже уровня моря, и где давление воздуха больше, точка кипения воды выше. * * * Почему полная бутылка держит огонь дольше, чем бутылка, которая наполовину полна. Бутылка, полная горячей воды, содержит больше тепла, чем бутылка, которая только половина заполнена. Различные вещи требуют разных количеств тепла, чтобы повысить до одинаковой температуры. Давайте возьмем немного воды и такое же количество чего -либо еще в мире, и сделаем их на пять градусов горячее, чем раньше.

10

We find that we have to put more heat into the water than into the other things. You need more time to heat water than to heat anything else, because you have to put more heat into it.

Мы находим, что мы должны вкладывать в воду больше тепла, чем в другие вещи. Вам нужно больше времени, чтобы нагреть воду, чем нагревать что -либо еще, потому что вы должны вкладывать в нее больше тепла.

11

So you need more time to cool water than anything else, because water has more heat in it which it must lose. Of course the more water we have, the more heat it has. * * * Is there any water in the sun?

Таким образом, вам нужно больше времени для охлаждения воды, чем что -либо еще, потому что у воды больше тепла, которое она должна потерять. Конечно, чем больше у нас воды, тем больше у него тепла. * * * Есть ли вода на солнце?

12

We are quite sure that there is no water in the sun. We know that there are both oxygen and hydrogen in the sun, as they are in the earth.

Мы совершенно уверены, что на солнце нет воды. Мы знаем, что на солнце есть как кислород, так и водород, как они находятся на земле.

13

We also know that in the sun oxygen and hydrogen have a great attraction for each other as they have in the earth. But there is no water in the sun, because the sun is so hot that oxygen and hydrogen cannot combine there.

Мы также знаем, что в солнечном кислороде и водороде есть большое притяжение друг к другу, как и на земле. Но на солнце нет воды, потому что солнце настолько жарко, что кислород и водород не могут там объединиться.
