The candle Burns more brightly in pure oxygen than in air because oxygen supports combustion observation hypothesis theory
1 answer
This is because oxygen is a highly reactive gas that readily combines with the fuel in the candle to produce heat and light. In air, the oxygen is diluted by other gases such as nitrogen and carbon dioxide, which do not support combustion as effectively. As a result, the candle burns more brightly and more quickly in pure oxygen because there is a higher concentration of oxygen available to react with the fuel.
