Because of the Thermonuclear fusion that goes on inside the core. Hydrogen nuclei undergo this process to form helium nuclei, giving out massive amounts of heat and light.
fusion
For nuclear fusion.
about the same temperature of 1000 suns
Its about 5670.16 degrees kelvin
5,000 degrees c
Inner of the sun Temperature is 14000°c and outer is 6000°c
4227 degrees Celsius to 5784
if it is high the density is high so if the temperature is low the density is low.
It is the cause of the differences in temperature at the equator and North and South Poles.
If you have a high temperature, you should not be doing this sort of work. If the cow had a high temperature and was ill then the meat will be infected and should not be eaten - so no you should not butcher it.
Hydrogen The sun is just made up of Hydrogen 74.9% and Helium 23.8%. The suns high pressure, and temperature fuses hydrogen into helium. The process is called Nuclear Fusion, this releases a lot of energy.
It's temperature hovers around 14 million degrees Centigrade.
