Question

l have a question that a fire needs oxygen to burn but why sun is continuously burning in space without oxygen. hey don,t give answer of nuclear fusion or fission because this process also needs oxygen.

Answer 1

The Sun does not "burn", like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Nuclear fusion occurs when one proton smashes into another proton so hard that they stick together...and release some energy as well. This energy then heats up the other materials (other protons and electrons and such) nearby.

Answer 2

Yo the sun ain't burnin it's jst a ball of gas wid continous nuclear fusion of hydrogen atoms to helium and then nucleur fission of helium into 2 hydrogen atoms which is an exothermic reaction which also gives out light
