Answer :
Final answer:
The temperature at the surface of the sun is closest to 5,500 degrees Celsius or 5750 Kelvin. This gives it a greenish-yellow color when viewed from space, with the color appearing more yellow from Earth due to our atmosphere scattering blue light. The sun's core temperature is significantly higher, around 15 million degrees Celsius.
Explanation:
The temperature at the surface of the sun is closest to option a) 5,500 degrees Celsius. This corresponds to around 5750 K (Kelvin), which is often used as the standard temperature scale in astronomical studies. This temperature gives the sun its characteristic color, a greenish-yellow when viewed from space, due to the balance of reddish and bluish wavelengths of light it emits. While it may appear more yellow from Earth's surface, this is due to our atmosphere scattering some of the shorter, blue wavelengths of sunlight, leaving behind the more long wavelength, yellow light.
It's worth noting that the temperature inside the sun, or its core temperature, is significantly higher, estimated to be 15 million degrees Celsius. The core is where most of the Sun's energy is generated.
