If you can travel to the sun in the future, you will find the following in the sun which of the following substances?
D) All of the above
Well, the answer is over. If you choose D, then congratulations! Like all stars, the sun contains almost every known element, including oxygen and hydrogen.In some places, the sun's oxygen and hydrogen elements can even combine to form water.
However, as everyone knows, the sun is hot. How hot is the sun? The surface temperature is about 5500 degrees Celsius, while the central temperature of up to tens of millions of degrees!
In fact, due to the high temperature of the sun, including oxygen and hydrogen, including almost all the atoms are in free floating around the state, each other can not be combined with each other to form molecules.
However, the sun's temperature is not uniform, some parts of the cold than the other parts. For example, sunspots - those large and dark spots on the sun's surface - are relatively cold.
The temperature of sunspots is lower because of their very strong magnetic field. The effect of strong magnetic field to most of the solar gas to the side, in the middle of the location of the lower temperature of the space, the temperature can be as low as 3000 degrees.
There, the temperature is low enough to allow atoms, including oxygen and hydrogen, to bond briefly with each other, so water will appear on the sun.
In fact,From the University of Waterloo (University of Waterloo) chemists have long been confirmed by spectral analysis of sunspots in the presence of water.
Of course, this does not mean that the sun has liquid water above the ocean, because the sun is still relatively hot. In fact, if you throw a large iron in the sunspot, it will evaporate immediately. Therefore, no water molecule can last a long time in the sun.
Sunspots do contain trace amounts of vapor in the form of water, which is still water on the sun!
