How hot is each one of the layers of the sun? (Beginner)

Hi i am doing a report for my 6 grade science class. I was wondering if you could answer the following question?

How hot is each one of the layers of the sun?

The centre of the Sun: about 15 million degrees Kelvin (K).

Radiative Zone: Temperature falls from about 7 million to about 2 million K across this zone.

Convection Zone: drops from 2 million K to 5800K in this zone.

Photosphere: about 5800K, although sunspots are about 3800K - that's why they are dark.

Chromosphere: 4300 to 8300 K from inside edge to outside edge

Corona: about 1 million degrees
