Is it possible for oxygen to be 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).
Can we liquify oxygen?
But can we liquify oxygen? As oxygen boils at 90 K /-183 °C and liquid nitrogen boils at 77 K /-196 °C we can use liquid nitrogen to liquify oxygen. The usual way to do this is to pass oxygen gas from a compressed gas cylinder through a coil of hollow copper pipe which is submerged in liquid nitrogen.
Can you turn oxygen to water?
In theory, it's easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water.
Is liquid oxygen 100% oxygen?
Liquid oxygen.
A liquid oxygen tank carries 100% oxygen as a very cold liquid. Oxygen turns into a liquid at -297 degrees Fahrenheit (-182.8 degrees Celsius). Manufacturers then compress it into a liquid oxygen tank.
Why is liquid oxygen so rare?
Liquid oxygen is much harder to find than liquid water because oxygen molecules aren't strongly attracted to other oxygen molecules. Every substance has a certain level of attraction between its molecules that pulls the molecules toward each other.
Is liquid oxygen O2 or O?
O2 describes the molecular structure of oxygen (or 'diatomic oxygen') if you like. It makes no difference whether its in gaseous, liquid, or 'supercritical' form.
Can oxygen freeze?
Liquid oxygen has a density of 1.141 g/cm3 (1.141 kg/L or 1141 kg/m3) and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 101.325 kPa (760 mmHg).
Is it possible to solidify oxygen?
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.
Can oxygen melt or boil?
Oxygen is a colourless odorless diatomic gas with an atomic number 8 and atomic weight 15.999. It has a melting point of -219°C and a boiling point of -183°C 1. It is mainly found in its diatomic form, O2.
Can we artificially make water?
While making small volumes of pure water in a lab is possible, it's not practical to “make” large volumes of water by mixing hydrogen and oxygen together. The reaction is expensive, releases lots of energy, and can cause really massive explosions.
Can we create water in lab?
Water can also be prepared using an eudiometer since the water vapor is formed which is the gaseous form of water molecule. So water can be prepared by burning oxygen and using an Eudiometer. Hence the correct option is C. Note: We need free hydrogen from the environment to prepare the water molecule.
What does 1 hydrogen and 1 oxygen make?
Water is composed of the elements hydrogen and oxygen, H2+O.
Can we breathe 100 pure oxygen?
In hospital settings, 100% oxygen may be delivered -- but even then only on a short-term basis, says Boyer -- less than 24 hours and preferably less than 12 hours. To breathe pure oxygen at that level for any longer can have toxic results, including "shock lung," or adult respiratory distress syndrome.
Is liquid oxygen explosive?
The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard.
Is liquid oxygen blue?
lower than those in the un- primed series, most of the absorption occurs in the red, yellow, and green region giving liquid oxygen its char- acteristic blue color.
Why is liquid oxygen blue?
Since the red and green bands are stronger, liquid oxygen appears blue, and because at the other wavelengths it is transparent, the blue is pale (lightly saturated.) The transition responsible for the pale blue color of liquid oxygen is the simultaneous excitation of two molecules from triplet sigma to singlet delta.
Why is liquid oxygen explosive?
A liquid oxygen explosive is a detonable mixture employing liquid oxygen as the oxidant of a combustible absorbent material. The detonation is the result of the rapid reaction of the combustible with the oxygen, which can occur over a wide range of oxygen concentrations.
How is liquid oxygen blue?
It contains two unpaired electrons due to which it is highly paramagnetic in nature. The two unpaired electrons create magnetic asymmetry due to which red light is absorbed in the visible spectrum. Due to absorption of red color, the characteristic color of liquid oxygen becomes pale blue.
Can humans breathe O1?
Originally Answered: Can we breath with O1 or O3 instead of O2? No. The oxygen radical (O•) is highly toxic to all forms of life. It is nonetheless produced in tiny quantities in living cells, but we have special enzymes for dealing with it.
Is oxygen shiny or dull?
Elements like O (oxygen) and H (hydrogen) are members of nonmetals. They can be a solid or a gas at room temperature. They have an appearance that is dull or without luster.
How does liquid oxygen taste?
Oxygen O₂ is a gas without color, taste or smell. It dissolves poorly in water, and boils at a temperature of -183 degrees Celsius. Oxygen in liquid form is light blue in color, and in solid form the element forms dark blue crystals. Oxygen melts at a temperature of -218.7 degrees Celsius.
Is pure oxygen explosive?
Oxygen is not flammable, but it can cause other materials that burn to ignite more easily and to burn far more rapidly. The result is that a fire involving oxygen can appear explosive-like.
Why can't we store oxygen?
Excess oxygen in the body will result in higher oxidation and formation of lethal free radicals compounds. That would be very damaging for the living system. In general, living systems , under normal conditions, do not have the capability to store oxygen, and air has more oxygen than a living system can utilize 100%.
Is solid oxygen blue?
Liquid oxygen and solid oxygen
Oxygen becomes solid at temperatures below -218.79℃. In both its liquid and solid states, the substances are clear with a light sky-blue colour. Liquid oxygen is a physical form of oxygen.
Can oxygen be created?
Currently, electrolysis is the most common way to produce oxygen from water, but this process requires electricity. Inspired by plants, artificial photosynthesis devices produce oxygen from water and sunlight using semiconductor materials coated with metallic catalysts – and thereby bypasses the need for electricity.
Can we touch liquid oxygen?
Liquid oxygen is very cold and can cause frostbite or burns if it comes in direct contact with your skin. Be careful not to touch the outlets or the parts carrying the liquid oxygen.
Can Argon be a liquid?
Argon is found in the atmosphere as a gas, it can be converted to a liquid by cooling it to a temperature below 302.4 degrees Fahrenheit. Some of the principal differences between argon gas and liquid argon include the following: Purity: Argon liquid is the highest form of purity to supply argon.
What is oxygen's color?
The gas is colorless, odorless, and tasteless. The liquid and solid forms are a pale blue color and are strongly paramagnetic.
Can oxygen create heat?
Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, although for airplane propulsion the fuel is usually a liquid.
Is liquid oxygen hot?
Liquid oxygen boils at –297.3 degrees Fahrenheit and is extremely cold. If permitted to contact skin or non-protective clothing, cold surfaces present on liquid oxygen systems such as valves, lines or couplings can cause severe frostbite or cryogenic burns.
Does water have DNA?
Depends where the water is from. And how it's been processed. Chemically pure water contains no DNA. However, almost any water in the real world will contain DNA.
Why can't we manufacture water?
Water is made of two hydrogen atoms and one oxygen atom. The process to combine hydrogen and oxygen is very dangerous though. Hydrogen is flammable and oxygen feeds flames, so the reaction to create water often results in an explosion.
Is h20 alive?
Water is non living. We talk about alive or dead only when it comes to living organisms. Living organisms are made of one or more cells and these cells are responsible for their living nature. They need nutrients, they do respiration, they do reproduction, they show movements and so on.
Is there any water on Mars?
Almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere. What was thought to be low-volume liquid brines in shallow Martian soil, also called recurrent slope lineae, may be grains of flowing sand and dust slipping downhill to make dark streaks.
Is there any new water on Earth?
The bottom line is that the amount of water on the Earth and in its atmosphere remains constant as it goes through the water cycle. The graphic below is a very basic illustration of water as it moves through the water cycle.
Is water wet scientific?
Most scientists define wetness as a liquid's ability to maintain contact with a solid surface, meaning that water itself is not wet, but can make other sensation. But if you define wet as 'made of liquid or moisture', as some do, then water and all other liquids can be considered wet.
What is H3O plus?
Hydronium is a cation that has a formula of H3O+. It often is made from a water molecule combined with a positively charged hydrogen ion.
What is H3O water?
H3O is known as hydronium ion. It is a positively charged ion that forms when a water molecule (H2O) gains a hydrogen ion (H+). In other words, it is a water molecule with an extra hydrogen ion attached to it.
Why is hydrogen not 1?
Earlier it was thought that hydrogen should be compared with other elements as it had atomic mass 1, but it had three isotopes which made its average atomic mass not equal to exactly 1.
Can humans breathe 35% oxygen?
Therefore, it makes sense that because humans and animals are adapted to breathing 21% oxygen in air, anything much different from 21% would be hazardous to our health. This is why OSHA considers any oxygen level below 19.5% as oxygen deficient or anything above 23.5% as oxygen enriched air.
Can humans breathe on Mars?
Mars does have an atmosphere, but it is about 100 times thinner than Earth's atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
Does oxygen make us age?
Oxidative stress causes cells and entire organisms to age. If reactive oxygen species accumulate, this causes damage to the DNA as well as changes in the protein molecules and lipids in the cell. The cell ultimately loses its functionality and dies.
Is hydrogen very flammable?
Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly. Hydrogen is a colorless, odorless, and tasteless gas. Natural gas and propane are also odorless, but a sulfur-containing (Mercaptan) odorant is added to these gases so that a leak can be detected.
Is Nitrogen is flammable?
Nitrogen gas is non-flammable but it can be dangerous to humans. Its odorless, tasteless, and colorless qualities exacerbate the dangers of breathing it in. Very high levels of pure nitrogen can cause dizziness, loss of consciousness, asphyxiation, and even death.
Why is oxygen not flammable?
Oxygen is not flammable because flames are the result of fuels reacting with Oxygen. Oxygen is not going to react with itself. Explosions are the result of fuels and Oxygen reacting very quickly, often because the two components have been mixed in the proper proportions, then ignited.
Can oxygen freeze?
Liquid oxygen has a density of 1.141 g/cm3 (1.141 kg/L or 1141 kg/m3) and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 101.325 kPa (760 mmHg).

Is liquid oxygen O2 or O?
O2 describes the molecular structure of oxygen (or 'diatomic oxygen') if you like. It makes no difference whether its in gaseous, liquid, or 'supercritical' form.
Can you solidify oxygen?
O2 changes from a gas to a liquid at a temperature of −182.96°C when it takes on a slightly bluish color. Liquid oxygen can then be solidified or frozen at a temperature of −218.4°C.
Is water naturally blue?
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.
Why is O2 colorless?
Gaseous oxygen is colorless because the visible range of light is reflected by gaseous oxygen. It doesn't absorb any of it, so we can see straight through it. But, when the oxygen forms a plasma, liquid, or solid, all the atoms get reconfigured and start emitting pale blue wavelength absorbing the rest.
Is 100% oxygen flammable?
Oxygen makes other things ignite at a lower temperature, and burn hotter and faster. But oxygen itself does not catch fire.”
Why is liquid oxygen so rare?
Liquid oxygen is much harder to find than liquid water because oxygen molecules aren't strongly attracted to other oxygen molecules. Every substance has a certain level of attraction between its molecules that pulls the molecules toward each other.
Does fire need oxygen?
There must be heat, fuel, and oxygen for a fire to exist.
Is liquid oxygen explosive?
The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard.
Is frozen oxygen blue?
The color of solid oxygen, on the other hand, ranges from light blue, pink-to-faint blue, faint-blue, orange, dark-red-to-black, and metallic in six of its different possible phases. You basically can have solid dioxygen in 6 different phases.
Does O8 exist?
"Red oxygen" is the nickname for O8. It only exists at extremely high pressures. What kind of bond does it have?
Can humans breathe 30% oxygen?
However, too much of a good thing isn't good either. If the oxygen concentration is much higher than 21%, we'll start experiencing oxygen toxicity, which can be fatal.
How do you make oxygen free water?
