What is the temperture of the sun's center?

Question

plz tell me

Answer 1

No one has ever gotten close enough to measure the temperature, but these are all very good theories.

Answer 2

The wheel is probably the most important mechanical invention of all time. Nearly every machine built since the beginning of the Industrial Revolution involves a single, basic principle embodied in one of mankind’s truly significant inventions. It’s hard to imagine any mechanized system that would be possible without the wheel or the idea of a symmetrical component moving in a circular motion on an axis. From tiny watch gears to automobiles, jet engines and computer disk drives, the principle is the same.
Based on diagrams on ancient clay tablets, the earliest known use of this essential invention was a potter’s wheel that was used at Ur in Mesopotamia (part of modern day Iraq} as early as 3500 BC. The first use of the wheel for transportation was probably on Mesopotamian chariots in 3200 BC. It is interesting to note that wheels may have had industrial or manufacturing applications before they were used on vehicles.

A wheel with spokes first appeared on Egyptian chariots around 2000 BC, and wheels seem to have developed in Europe by 1400 BC without any influence from the Middle East. Because the idea of the wheel appears so simple, it’s easy to assume that the wheel would have simply "happened" in every culture when it reached a particular level of sophistication. However, this is not the case. The great Inca, Aztec and Maya civilizations reached an extremely high level of development, yet they never used the wheel. In fact, there is no evidence that the use of the wheel existed among native people anywhere in the Western Hemisphere until well after contact with Europeans.

Even in Europe, the wheel evolved little until the beginning of the nineteenth century. However, with the coming of the Industrial Revolution the wheel became the central component of technology, and came to be used in thousands of ways in countless different mechanisms

Answer 3

Temperature of core ~15.71 Million degrees Kelvin

"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.[10] 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."

Temperature of surface (effective) 5,778 K
Temperature of corona 5 MK

Average density 1,409 kg/m³ (88 lb/ft³)
This is the important thing about the sun. It is so hot because it is so dense, it is so dense that the heat turns it into a plasma and induces fusion. The high pressure (from the density) started the whole process.

The sun is in a tug of war; the force of gravity tries to collapse it, the heat tries to expand it, the centrifugal force tries to rip it apart and the explosion of fusion just tries to blow it all into pieces. Because the sun is so large gravity is the winner.

Answer 4

New York: Grolier, 1996: Vol 17S " so that at the center of the sun we should find a very hot core with a temperature that reaches about 27,000,000 °F (15,000,000 °C)"

Answer 5

The temperature at the sun's core is estimated at about 24 million degrees F.
At the surface, its 9,000 degrees F.
The corona's temperature is 9 million degrees F.

Answer 6

10M degrees F at an enormous pressure.

Answer 7

one hundred billion degrees, give or take a few degrees.
