Q:
why is the sun so hot?

A:
The sun is hot because the atoms deep inside the sun are undergoing nuclear fusion. Nuclear fusion releases a lot of energy. This energy excites all the other atoms in the sun, and causes them to move about. This is what heat is. So the nuclear reactions inside the sun cause the sun to be hot.
Thank you for your question.
