Not exact matches

There are basically two types of lines, those produced by collisions between the atoms or ions and the electrons in the surrounding gas, which are called collision lines, and which are very bright for elements such as oxygen, nitrogen and neon, and lines which are produced when ions capture free electrons, which are called recombination lines, and which are bright only for those gases with the highest abundances in the interstellar medium: hydrogen and helium.

At high heat, the cladding interacts with the surrounding water vapor, binding tightly to the oxygen and freeing the hydrogen, which escapes as a gas.
