How Maney temperature of sun core?

Answer 1

The core's temperature is estimated as approx 15.71 million degrees Kelvin (24,500,000° F). The corona is 5 million degrees Kelvin (9,000,000° F). Whereas the photosphere (the surface) is a mere 5,778 degrees Kelvin (9,953° F).

Confusingly, elsewhere in the same Wikipedia article, we find the statement:

"The core of the Sun is considered to extend from the center to about 0.2 solar radii. It has a density of up to 150,000 kg/m^3 (150 times the density of water on Earth) and a temperature of close to 13,600,000 kelvins"

(Presumably there is some disagreement amongst scientists on the precise figure?)

The outermost layers of the Sun, beyond the photosphere are reported by this same article to be (in order outwards):

The temperature minimum region:
The chromosphere:
The transition region:
The corona:

The coolest layer of the Sun is a temperature minimum region about 500 km (300 mi) above the photosphere, with a temperature of about 4,000 K. This part of the Sun is cool enough to support simple molecules such as carbon monoxide and water, which can be detected by their absorption spectra.

Above the temperature minimum layer is a thin layer about 2,000 km (1,000 mi) thick, dominated by a spectrum of emission and absorption lines. It is called the chromosphere from the Greek root chroma, meaning color, because the chromosphere is visible as a colored flash at the beginning and end of total eclipses of the Sun. The temperature in the chromosphere increases gradually with altitude, ranging up to around 100,000 K near the top.

Above the chromosphere is a transition region in which the temperature rises rapidly from around 100,000 K to coronal temperatures closer to one million K. The increase is because of a phase transition as helium within the region becomes fully ionized by the high temperatures. The transition region does not occur at a well-defined altitude. Rather, it forms a kind of nimbus around chromospheric features such as spicules and filaments, and is in constant, chaotic motion. The transition region is not easily visible from Earth's surface, but is readily observable from space by instruments sensitive to the far ultraviolet portion of the spectrum.

The corona is the extended outer atmosphere of the Sun, which is much larger in volume than the Sun itself. The corona merges smoothly with the solar wind that fills the solar system and heliosphere. The temperature of the corona is several million kelvin.

So, as you can see the question "what is the temperature of the Sun?" has no one, simple answer!

Answer 2

Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun's core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter.

Answer 3

Gases in the core are about 150 times as dense as water and reach temperatures as high as 16 million degrees C (29 million degrees F). The Sun’s energy is produced in the core through nuclear fusion of hydrogen atoms into helium.

Answer 4

what is the meaning of how maney temperature of suns core?

Answer 5

The core's temperature is 15.71 million degree. But its not as hot as the outside.

The core of the Sun is considered to extend from the center to about 0.2 solar radii. It has a density of up to 150,000 kg/m3 (150 times the density of water on Earth) and a temperature of close to 13,600,000 kelvins (by contrast, the surface of the Sun is close to 5,785 kelvins (1/2350th of the core)). Recent analysis of SOHO mission data favors a faster rotation rate in the core than in the rest of the radiative zone[9]. Through most of the Sun's life, energy is produced by nuclear fusion through a series of steps called the p-p (proton-proton) chain; this process converts hydrogen into helium. The core is the only location in the Sun that produces an appreciable amount of heat via fusion: the rest of the star is heated by energy that is transferred outward from the core. All of the energy produced by fusion in the core must travel through many successive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles.

About 3.4×1038 protons (hydrogen nuclei) are converted into helium nuclei every second (out of about ~8.9×1056 total amount of free protons in Sun), releasing energy at the matter-energy conversion rate of 4.26 million tonnes per second, 383 yottawatts (383×1024 W) or 9.15×1010 megatons of TNT per second. This corresponds to extremely low rate of energy production in the Sun's core - about 0.3 μW/cm³, or about 6 μW/kg. For comparison, ordinary candela produces heat at the rate 1 W/cm³, and human body - at the rate 1.2 W/kg. Use of plasma with similar parameters as solar interior plasma for energy production on Earth is completely impractical - as even modest 1 GW fusion power plant would require about 170 billion tonnes of plasma occupying almost one cubic mile. Thus all terrestrial fusion reactors require much higher plasma temperatures than those in Sun's interior to be viable.
