Its melting point is -218.79 °C.
Oxygen is usally a Gas. It can be liquified if cooled past its boiling point. And it can become a solid if cooled past its melting point. Oxygen can be in all three states but is usally in the state of Gas.
Melted/Liquified
NO!!!! It can be combined with metal ores, such as iron oxide (rust) If cooled to a very low temperature it will be come a liquid. If cooling continues it will become a solid. It has an allotrope, named 'Ozone'(O3) , which is three oxygen atoms combined in a triangular structure. NB Oxygen is a very reactive gas.
Nitrogen and oxygen can be separated by using a process called fractional distillation, which takes advantage of their different boiling points. Air is cooled and liquified, then gradually heated until it begins to vaporize. Since oxygen has a lower boiling point than nitrogen, it vaporizes first, allowing for the separation of the two gases.
Yes, LPG (liquefied petroleum gas) is stored in liquid form under pressure in a gas cylinder. This allows for a larger volume of gas to be stored in a smaller space, making it easier for transportation and use.
Oxygen is not flammable but is necessary for combustion.
Can you breathe liquid? No, so oxygen must be a gas because that's what everyone breathes.
Milk is a liquid
LIQUIFIED NATURAL GAS
Liquified Petroleum
putting it in liquified gas.
Liquified nickel and iron.

Yes, Liquified Petroleum Gas is a Gas. It is a mixture of butane and propane. Also ethyl mercaptan is added to LPG to detect the gas leakage.
