Why is the sun s temperature low inside and high outside?

In fact, the core temperature is higher than the surface temperature. It takes millions of years for light to travel from the inner core of the sun to the surface of the sun. This is because of the action of gravity.

The temperature of the sun is halved from the core to the edge of the core.

Let's put it in a different way. In fact, the universe is the action of three mechanics, electromagnetic force, centrifugal force, and gravitational force.

The core of the sun is in a state of ultra-high pressure and ultra-high temperature, so that elements such as hydrogen and helium are pressed into a liquid or even almost solid form.

The extremely huge amount of energy released by nuclear fusion is generated inside.,Normally, it will throw everything around it outwards like a nuclear bomb** on the earth.。。 Extreme projectile.

But there is a force that inhibits this throwing reaction. That's gravity.

Gravitational constraints make it impossible to throw any element out of the equivalent of 1010 million tonnes of TNT**.

Now the sun is in a period of equilibrium, which means that his ** force is not enough to break free from gravity, and at the same time, his gravitational force is not enough to oppress his ** force to collapse.

The sun is turning mass into energy all the time. That is, the sun is getting smaller. When one day the mass decreases and its gravitational pull is not enough to withstand the energy generated by the internal nuclear reactions, the sun expands and expands.

Become a red giant, and now deduce that the sun will engulf the earth by then.

The volume of the sun will expand hundreds of times that of the present, and then it will rise to another phenomenon, because the volume of the sun will become larger, the external radiation surface will also become larger, and the sun will lose a large amount of material in a very short time, in the form of the current solar wind.

Without the pressure matter, nuclear fusion will be reduced, gravity will begin to gain the upper hand, and the sun's mass will accelerate towards the center. Collapsed into a white dwarf the size of the Earth.

You're referring to the temperature of the sun's atmosphere, right? The temperature of the sun's core is as high as 15 million k, which is the hottest place in the sun.

The temperature of the upper layer of the solar photosphere is about 5700 K, and the temperature of the chromosphere above the photosphere rises from 6000 K at the bottom to tens of thousands of K at the top. What's more, the temperature of the corona outside the chromosphere is as high as 1 million K. This phenomenon remains a mystery to this day.

Some speculate that the core of the sun has some kind of material that carries a lot of heat energy scattered outward, and when it reaches the corona, it is suddenly released, creating an abnormally high temperature. Later, it was proposed that there are many high-temperature charged plasma rings between the surface of the sun and the corona, and the current flows through the giant rings to heat the plasma, and it is the giant rings that transfer heat to the corona. Recently, it has been suggested that there are many magnetic field beams or blankets between the surface of the Sun and the corona, and that the repeated annihilation or reconnection of magnetic field lines transfers heat to the corona.

It is the internal factors that play a decisive role in the temperature of the sun. The sun's nuclear fusion is very violent, with a core temperature of more than 10 million degrees Celsius, while the corona is only about 3 million degrees, which does not violate the basic principles of thermodynamics. As for the temperature difference between the photosphere, chromosphere and the corona, the heat source, the heat transfer mode and the transfer channel should be considered.

It's the same as lighting a candle, the flame of the candle has three layers, the outermost layer is the hottest instead of the innermost!

Maybe the sun is too big, and the fusion of hydrogen nuclei absorbed on the outside is more violent, but isn't it ** if it's fierce inside, hehe.

The sun's energy comes from nuclear fusion, and the coronal layer is where thermonuclear fusion really takes place.

The reason, the materialist world is not real!

First of all, the sun does give the earth light and heat, but the heat provided by the sun is in the form of electromagnetic radiation, and after the sunlight reaches the earth, it will interact with the earth's atmosphere, so that the temperature is generated. In this respect, the lower the altitude, the less solar energy you get, and that's no problem.

The problem lies in the different effects of different gases on sunlight. Sunlight is divided into different wavelengths, and different atmospheres have different effects on different wavelengths of sunlight, which generally include reflection, refraction and absorption.

Radiation:

In the tropospheric atmosphere, oxygen, hydrogen, and carbon dioxide cannot directly absorb short-wave solar radiation, only refraction and reflection occur, and the higher the altitude, the thinner the air. It is the ground that ultimately absorbs the amount of solar energy. When the ground absorbs the amount of sunlight, the temperature increases, and then the atmosphere is released with infrared-based energy, which is called ground radiation.

Infrared rays are absorbed by carbon dioxide and water vapour in the atmosphere, which increases the temperature of the air. In the troposphere, the temperature of the atmosphere decreases not according to the distance from the sun, but according to the distance from the ground, which is why the higher the altitude, the lower the temperature.

The atmosphere of the Sun can be divided into three layers: the photosphere, the chromosphere, and the corona from the inside to the outside. The temperature of the corona is very high, up to 2 million K;

Incredibly, the photosphere, which is closest to the center of the sun, has a temperature of several thousand degrees, and the chromosphere, which is a little farther away, has a temperature of tens of thousands of degrees to tens of thousands of degrees. And the coronal layer, which is farthest from the center of the sun, has a temperature of up to one million degrees. Scientists have yet to find a reasonable explanation for what the laws of thermodynamics mean by the anomaly that determines that heat does not flow from a cold to a high temperature.

Your statement is incorrect, it should be said that the outer temperature of the solar atmosphere is higher than the inside. The inside of the sun refers to the core, radiation layer, and troposphere, and the outside of the sun refers to the photosphere, chromosphere, and corona, and the outside of the sun usually refers to the solar atmosphere, only the outer atmosphere is warmer than the inside.

The temperature of the sun's core is tens of millions of degrees Celsius, about 15,000,000, and it is decreasing from the inside to the outside.

The temperature of the radiating layer, which is lower than that of the core, tends to decrease from the inside to the outside.

The temperature of the troposphere is lower than that of the radiation layer, the temperature of the innermost region is the highest, and the temperature of the outermost region is the lowest, but because the temperature of the outermost particles decreases, the particles with insufficient energy will fall back inside, reheat and fly out, and so on, so the temperature in the middle region is unstable.

The temperature of the photosphere is several thousand degrees Celsius, the innermost region is about 8000, the middle region is about 6000, and the outermost region is about 4000, showing a decreasing trend from the inside to the outside.

The temperature of the junction between the photosphere and the chromosphere is several thousand degrees Celsius, about 4300 to 4500

The temperature of the chromosphere is several thousand to tens of thousands of degrees Celsius, and it tends to increase from the inside to the outside.

The temperature of the coronal layer is several million degrees Celsius, about 2,000,000, and it tends to increase from the inside to the outside.

The reason may be that the decrease in the gravitational pull of the sun makes the solar atmosphere more violent, and therefore the temperature increases; Or a large amount of energy accumulates in the photosphere particles, which is gradually released in the chromosphere and corona, so that the temperature rises; Or in the chromosphere and corona layer the particles become a form that converts most of the energy into heat, thus increasing the temperature. At present, there is no scientific explanation, and scientists are not yet able to explain this phenomenon. The above reasons are only personal speculation and are for reference only.

One view is that if there are clouds on the surface of the earth in the morning, and if you look at the sun through the clouds, the sun will appear to be large. When the clouds dissipate at noon, the sun appears small, but the size of the sun has not changed.

Another point of view is that the sun has a different altitude and a different refractive index of the atmosphere, and in the morning the sun has a low altitude angle and a large refractive index, so the sun looks big. There is also a point of view:

It seems that the sun is a little bigger in the morning than at noon because of the illusion of the eyes. We look at a white figure that is larger than a black figure of the same size. This is called "photoosmosis" in physics

When the sun rises, the surrounding sky is dark and dark, so that the sun appears bright, and at noon, the sky is bright, and the difference between the brightness of the sun and the backing is not so great, which is why it seems that the sun is bigger in the morning than at noon. In short, the sun is at the same distance from us in the morning and at noon, so its size is the same Also, is it hotter at noon than in the morning, is it because the sun is closer to us at noon than in the morning? Neither is it.

So why? Noon is hotter than morning because the sunlight is directly on the ground at noon, and the morning sunlight is obliquely on the ground. So noon is hotter than morning.

In fact, the heat and coldness of the weather are mainly determined by the temperature of the air. The main factor affecting the air temperature is determined by the intensity of the sun's radiation, but the solar heat is not the main reason for the direct increase in air temperature. Because the heat energy directly absorbed by the air into the sunlight is only a small fraction of the total heat energy of solar radiation, most of which is absorbed by the ground.

The ground absorbs the heat of solar radiation, and then conducts it upwards to the air through heat transfer methods such as radiation and convection, which is the main reason for the increase in temperature. In short, the fact that the sun is hot at noon and colder in the morning is not because the sun is far or near our earth. For details.

In the Northern Hemisphere during the summer, the Earth's axis is tilted in the direction of the Sun, so the position of the Sun appears higher in the summer.

The intersection angle between the white plane of the moon and the ecliptic plane of the earth is not large, it is 5 degrees and 9 minutes, and in winter, the direction of the earth's axis is opposite to that of summer, and it is biased in the opposite direction of the sun, which is similar to the height of the sun in summer, and the moon appears high in winter.

This is the northern hemisphere, and the southern hemisphere is the opposite.

The temperature of the sun's core is as high as 15 million degrees Celsius, and 600 million tons of hydrogen are fused into helium every second and then sent to the sun's surface. The surface of the Sun, also known as the optosphere, has a lower temperature of 5500 C. Taida Langyang is a natural nuclear reactor suspended in the air, which releases an astonishing amount of energy through nuclear fusion.

It is like a factory in Chunchang, and there is a constant reaction in it to produce a lot of energy, resulting in a very high temperature.

made by hydrogen. Fusion.

for helium. Thermonuclear counter-cautious.

When it happens, the frankness releases the energy of great reverence.

Because there is a nuclear fusion in the center of the sun at all times! (i.e. the power of the hydrogen bomb**) to produce a lot of energy!

Scientists have grasped the dialectical relationship between temperature and light, and gradually grasped the temperature of the sun. The temperature of the sun can be estimated from its color, which is usually seen as golden yellow, and the color of the sun is 6000 degrees Celsius, taking into account the absorption of the earth's atmosphere. The temperature corresponds.

In addition, it can be demonstrated by measuring the total radiance of the sun, spectroscopic analysis, and radio technology.

The temperature on the sun is 6000 degrees Celsius.

Of course, this is the surface temperature of the sun. As for the temperature of the center of the sun, it is estimated to be about 20 million degrees Celsius.

A lot of hydrogen. Helium gas combustion.

The temperature of the Sun's core is as high as 15 million degrees Celsius, where 600 million tons of hydrogen are fused into helium and then sent to the surface of the Sun. The surface of the Sun, also known as the optosphere, has a lower temperature of 5500 C. The sun is a natural nuclear reactor suspended in the air, and it releases amazing energy through nuclear fusion.

The sun is like a factory, and there are constant reactions in it that produce a lot of energy, resulting in a very high temperature.

Nuclear fusion reactions continue inside the Sun. Nuclear fusion reaction refers to the fusion of hydrogen atoms to form helium atoms under high temperature and high pressure conditions, and release neutrons, this process will release a large amount of energy, so it will cause the high temperature of the sun.

With such a big piece of coal burning, can the temperature not be high!

Despite the heat exchange between the atmosphere and the underlying surface, there is no doubt that the Sun is one of the main sources of heat on the Earth's surface.

The solar radiation constant (the amount of solar radiation received per second per unit area perpendicular to the sun's rays from the apex of the atmosphere from the average distance between the Sun and the Earth) is constant, but it does not mean that the power of heat received per unit area of the Earth's surface is also certain.

It is easy to understand that the higher the intensity of radiation received, the higher the temperature. Therefore, it is not difficult to understand the following three points: (1) why noon is warmer than morning and dusk or night, (2) why the temperature is higher in low latitudes than in high latitudes, and (3) why the temperature in summer is warmer than in winter.
