o it's temperature is 5,500 degrees celsius to 6,000 degrees celsius.
o it's temperature is 6,000 degrees celsius to 20,000 degrees celsius.
it's temperature is 20,000 degrees celsius to 2,000,000 degrees celsius.
it's temperature is 2,000,000 degrees celsius to 3,000,000 degrees celsius.

The temperature of the Sun's middle most layer is 6,000 degrees Celsius to 20,000 degrees Celsius.

Explanation:

The sun is basically divided into inner and outer layer.The inner layer consists of Core, Radiative Zone and Convection Zone.The outer layer has Photosphere, chromosphere, transition region and corona.The chromosphere is the middle layer that can vary its temperature 6,000 degrees Celsius to 20,000 degrees.For most reason the temperature of chromosphere can be taken around 7700 degree Celsius but it varies.
