Making and playing with Liquid Oxygen

TL;DR

Liquid oxygen can be produced by condensing oxygen gas using liquid nitrogen, and it exhibits unique properties such as intense reactivity and paramagnetism.

Transcript

Oxygen is most commonly seen as gas but under certain conditions we can see it as liquid. It is actually the temperature and the pressure that determines whether something will exist as a gas solid or liquid. In the atmospheric pressure that we live in oxygen is a gas but if we increase the pressure enough or lower the temperature enough we can put... Read More

Questions & Answers

Q: How is liquid oxygen produced?

Liquid oxygen is produced by condensing oxygen gas using liquid nitrogen, which cools down the oxygen gas to its liquid state.

Q: What are the practical applications of liquid oxygen?

Liquid oxygen is commonly used as a liquid oxidizer for spacecraft. It can also be used in various medical and industrial applications.

Q: What are some properties of liquid oxygen?

Liquid oxygen is highly reactive and can cause intense reactions when it comes into contact with substances such as steel wool or a flaming match. It also exhibits paramagnetic properties, allowing it to be influenced by a magnetic field.

Q: How is liquid oxygen stored and handled?

Liquid oxygen is typically stored in vacuum thermos containers to keep it at very low temperatures. It should be handled with caution due to its reactivity and potential hazards.

Summary & Key Takeaways

• Oxygen can exist as a gas, liquid, or solid, depending on temperature and pressure.

• Liquid oxygen can be generated by condensing oxygen gas using liquid nitrogen.

• Liquid oxygen is highly reactive and can cause intense reactions when in contact with certain substances.
