Answer 2

Acetylene is created when calcium carbide, which is a man made substance, reacts to water. It can keep indefinitely, and is used in welding with separate cylinders of oxygen and acetylene gas, which is kept at high pressure. Cylinders are stored upright in order to keep the stored gas stable.

It is a colorless gas with a strong garlic odor. It burns at 5,600 degrees Fahrenheit with a neutral flame and is used for hard facing, heating, brazing, cutting and welding. Note that acetylene should not be compressed above the level that causes instability which is 15 PSI.
