Question

when there is no oxygen on sun's☀️ surface... How does it burns ??​

Answer 1

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. This heating eventually grows out from the center (or core) of the star to the outside, finally leaving the surface and radiating out into space to be the heat and light we know stars emit.

Answer 2

Ello user !!!!!!!!!

Here is your answer,

===================================================

So, the Sun can "burn" hydrogen to helium without the need for oxygen.

It should be noted that in the presence of carbon, nitrogen and oxygen, stars heavier than the Sun may burn hydrogen to helium by using the C, N and O as catalysts.

Even in these stars, however, an absence of oxygen does not prevent nuclear burning.

HOPE THIS HELPS YOUU :)
