What do you observe when you pace a glowing splint in a glass plate and pour oygen into it?

Answer 1

Aldrin ... I guess you meant "oxygen," correct? And when you say "splint," I'm picturing a small piece of wood.

If you "pour" oxygen on it, I guess you're referring to liquid oxygen. I'm not sure where you'd get your hands on oxygen in liquid form. If you meant oxygen in gaseous form from a compressed tank of the gas, I suspect the flame would immensely intensify, perhaps to a dangerous level, but it would burn out faster than it would if it were permitted to burn in a normal atmosphere of regular air.

Do you remember the Apollo I fire? Perhaps not. See my link below and scroll down to the section called "The Accident." This is what happens to a fire that is intensified by a pure oxygen environment.

Answer 2

This is a test for gases. In high school I did this experiment with hydrogen gas, oxygen gas, and carbon dioxide gas. When you place the glowing splint into a test tube filled with oxygen, it will reignite.

For interest:
If you place a lit splint into a tube filled with hydrogen, you will witness a small explosion that will suffocate the flame, and it will go out. For Carbon Dioxide, a lit splint will just be put out as a result of the absence of oxygen.

Answer 3

The classic test for oxygen is that it re-lights a glowing splint.

Answer 4

A flame?
