The amount of oxygen in a submarine is carefully managed to ensure the safety and comfort of those on board. Modern submarines generate oxygen through electrolysis (splitting water into hydrogen and oxygen) and by using oxygen candles that release oxygen when burned. Typically, a submarine is equipped with a 90-day supply of oxygen, ensuring it can remain submerged for extended periods without needing to surface for air replenishment.
FAQs & Answers
- How do submarines generate oxygen while submerged? Submarines generate oxygen primarily through electrolysis, which splits water into hydrogen and oxygen, and by using oxygen candles that release oxygen when burned.
- How long can a submarine stay underwater without resurfacing for oxygen? Typically, submarines carry a 90-day oxygen supply, allowing them to remain submerged for extended periods without requiring surface air replenishment.
- What are oxygen candles used in submarines? Oxygen candles are chemical devices that release oxygen when burned, serving as a backup or supplemental oxygen source in submarines.
