What are burning gases in the Sun?

Answer 1

In the Sun hydrogen is converted to helium. Both are PLASMA.

It's a very common misconception that the fusion in the sun happens with gas. However, the heat created by this fusion heats up the gasses so much that the individual electrons become loose from the atom. We call this state plasma.

Answer 2

Although it is a close description, the sun does not burn. It undergoes nuclear fusion, primarily of hydrogen to helium and at the same time producing massive amounts of energy. Secondly, it does not release any gas; all of the Sun's material is in the form of plasma, the fourth state of matter.

Answer 3

The burning gases in the Sun are mainly hydrogen and helium undergoing nuclear fusion in its core. This process releases immense amounts of energy in the form of light and heat, which ultimately powers the Sun and sustains life on Earth.

Answer 4

Hydrogen. It doesn't really burn though,

because burning is an oxidation process.

Hydrogen fuses to form helium,

at least for stars in the main stage
