Is O2 a fluid?
Liquid oxygen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid oxygen has a boiling point of –297°F (–183°C). Oxygen is often stored as a liquid, although it is used primarily as a gas.
What type of substance is 02?
Oxygen is Earth’s most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O2.
Is oxygen a fluid at room temperature?
Oxygen is a gas at room temperature. If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature.
Is o2 a molecule?
Oxygen is found naturally as a molecule. Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O2. Oxygen is normally found as a molecule. It is called dioxygen.
Is O2 a molecule?
Is O2 homogeneous or heterogeneous?

Can o2 be a solid?
Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.
What temperature is o2 a liquid?
Liquid oxygen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid oxygen has a boiling point of –297°F (–183°C).
Is O2 diamagnetic or paramagnetic?
Because the O2 molecule has two unpaired electrons, it is paramagnetic. Consequently, it is attracted into a magnetic field, which allows it to remain suspended between the poles of a powerful magnet until it evaporates.
Why is O2 a molecule?
The O double bond O bond is strong and this means that, in the absence of something else to react with, eg a metal or hydrogen, two oxygen atoms will readily react with one another to form an oxygen molecule.
Can you breathe liquid oxygen?
Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid (such as a perfluorocarbon), rather than breathing air. By selecting a liquid that is capable of holding large amounts of oxygen and CO2, gas exchange can occur.
