Can we have 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. It has many commercial uses in industry and medicine.
Is liquid oxygen edible?
Do not do this. First, you'd have the neck-freezing-and-possibly-exploding scenario mentioned in another answer. But as an added bonus, liquid oxygen causes rapid oxidation of organic material. This is a fancy way of saying it's going to start your mouth on fire and then blow it up.
How strong is frozen oxygen?
Solid oxygen was found to behave as a plastic material with a shear strength of approximately 0.3 MPa 10 K below its melting point. Solid oxygen becomes increasingly stronger and brittle as its temperature is decreased, giving a shear strength of over 3.5 MPa at low temperatures.
Can you touch liquid oxygen?
Liquid oxygen is very cold and can cause frostbite or burns if it comes in direct contact with your skin.
Can we breathe 100% O2?
Extended exposure to above-normal oxygen partial pressures or shorter exposures to very high partial pressures can cause oxidative damage to cell membranes leading to the collapse of the alveoli in the lungs. Pulmonary effects can present as early as within 24 hours of breathing pure oxygen.
Is solid oxygen strong?
The approximate shear strength of solid oxygen was measured as a function of temperature, increasing from 0.31 MPa at 45 K, to 4.46 MPa at 18 K. Solid oxygen was found to undergo plastic deformation at high temperatures, becoming increasingly strong and brittle as its temperature was decreased.
Can you Flavour oxygen?
Some oxygen bar companies offer safe water-based aromas for flavoring in order to maintain compliance and stay within FDA guidelines. Oxygen may also cause serious side effects at excessive doses.
Does oxygen have a flavor?
Oxygen is a colorless, odorless, tasteless gas. It is the most plentiful element in the rocks of Earth's crust.
Why is oxygen written as O2?
Because each oxygen molecule has two oxygen atoms, it is written with a \[2\] . Note: We breathe diatomic oxygen molecules, which are made up of only two oxygen atoms. Diatomic oxygen is a relatively stable oxygen molecule that accounts for roughly \[21\% \] of the air we breathe.
Can you survive 10% oxygen?
Breathing air containing 6 to 10 percent oxygen results in nausea, vomiting, lethargic movements, and perhaps unconsciousness. Breathing air containing less than 6 percent oxygen produces convulsions, then apnea (cessation of breathing), followed by cardiac standstill.
Why is oxygen blue?
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 we freeze helium?
That's due to the fact that Helium has the lowest boiling and freezing points of any other known substance. Helium happens to be the only element that can't be solidified or frozen at normal atmospheric pressure. Only once you apply a pressure of 25 atmospheres at Helium's freezing point of −458 °F can you solidify it.

How cold is solid 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 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.

Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can't see properly, and your lungs, so you can't breathe normally. So breathing pure oxygen is quite dangerous.
Why is O2 zero?
For oxygen, the standard state is O2 gas. By definition, the standard enthalpy of formation of an element in its standard state is zero. This is because there is no formation process needed for an element in its standard state; it is already in that state.
Is oxygen O2 or just O?
The Symbol of oxygen is 'O' and the formula for oxygen is 'O2'. The difference between the symbol and formula is that the symbol 'O' is a free oxygen atom whereas O2 is two oxygen atoms chemically bound to form an oxygen molecule.
Do we breath O or O2?
If you remember anything from your physics and chemistry lessons, you will recall that among the gases that make up the atmosphere and the air we breathe is oxygen (O2). It is often said that oxygen is necessary for life, but in fact, it is dioxygen.
What if we lived in 100% oxygen?
The overall interchange of "air" in the lungs would drop and mucus would accumulate in the damaged tissues of the lungs, making it even more difficult to breathe. Eventually this person would die from asphyxiation/suffocation, even in an atmosphere full of available 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.
Can you breathe 40% oxygen?
It is also shown that, breathing 40 per cent oxygen is usually sufficient for therapeutic purposes and does not cause increased retention of carbon dioxide.
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 oxygen so rare?
The reason is simple. Oxygen is so reactive that an atmosphere can only contain a significant amount if there is something continuously producing large amounts of it. On earth, that is life or more specifically living things that photosynthesise.
What color is pure oxygen?
Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere.
What freezes at 0 Kelvin?
Answer and Explanation: Water freezes at absolute zero. Even water freeze at zero degrees Celcius but water molecule does not come to rest at this temperature. But at -273.15 degrees Celsius (absolute zero/ 0 kelvin), the molecular movement of water comes to rest or becomes minimal.

The boiling point of helium is 4.2 K or -269 °C. Liquid helium is the coldest liquid on earth.
What does space smell like NASA?
Overall, astronauts often compare the smell of space to "hot metal, burnt meat, burnt cakes, spent gunpowder and welding of metal," according to Steve Pearce, a biochemist and CEO of Omega Ingredients, who combed through astronaut interviews to help him craft a NASA-commissioned scent.
Is there a smell in space?
We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.
Is there a smell with Covid?
Parosmia, also called "COVID smell," typically occurs months after you have COVID. 23 This could happen even if you didn't lose the sense of smell when you had COVID.
Is 30% oxygen flammable?
Though not flammable itself, oxygen vigorously supports combustion. Materials that do not burn in air may burn in oxygen-enriched air (>23% oxygen). Some materials can even become spontaneously flammable in oxygen or oxygen-enriched air.
Is pure oxygen flammable?
To summarize, oxygen is not flammable by itself, but it can cause other objects to ignite quickly and rapidly (a property that makes oxygen an excellent oxidizing agent) and set things on fire. This is also why, if a fire has an abundant supply of oxygen, it can become massive and sometimes even explosive!
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.
Is oxygen in ice?
In the solid state (ice), intermolecular interactions lead to a highly ordered but loose structure in which each oxygen atom is surrounded by four hydrogen atoms; two of these hydrogen atoms are covalently bonded to the oxygen atom, and the two others (at longer distances) are hydrogen bonded to the oxygen atom's ...
Is solid oxygen strong?
The approximate shear strength of solid oxygen was measured as a function of temperature, increasing from 0.31 MPa at 45 K, to 4.46 MPa at 18 K. Solid oxygen was found to undergo plastic deformation at high temperatures, becoming increasingly strong and brittle as its temperature was decreased.
How cold is dry ice?
The temperature of dry ice is approximately -78 degrees C (-109 F). Unless it is maintained in an environment colder than that, it will sublimate (go directly from solid to gas). One pound of dry ice will produce 250 liters of carbon dioxide gas at atmospheric pressure.
Can we breathe 100% pure oxygen?
Pure oxygen can be deadly. Our blood has evolved to capture the oxygen we breathe in and bind it safely to the transport molecule called haemoglobin. If you breathe air with a much higher than normal O2 concentration, the oxygen in the lungs overwhelms the blood's ability to carry it away.
Does more oxygen make you taller?
If there was a higher percentage of oxygen in our atmosphere, would humans and animals grow bigger? Probably not. Except for some arthropods. Their breathing apparatus depends on diffusion not actively pumping air so one limit on their size is O2 being able to diffuse inwards.
Can you breathe 10% oxygen?
Breathing air containing 6 to 10 percent oxygen results in nausea, vomiting, lethargic movements, and perhaps unconsciousness.
Is Mars air toxic?
TOXICITY OF MARTIAN ATMOSPHERIC GASES
There is a small amount of toxic carbon monoxide (0.07 percent), as well as traces of ozone up to 0.2 ppm.
Is it safe to touch Mars?
Your fingers could get a bad case of frostbite/blistering if you handle freezing rocks or regolith for an extended period of time. Also, the “atmosphere” is basically vacuum, so your skin and joints can get badly damaged after a while of touching Mars.
Can we breathe on Jupiter?
First things first, Jupiter's atmosphere has no oxygen. So make sure you bring plenty with you to breathe. The next problem is the scorching temperatures. So pack an air conditioner.

✔ Oxygen is a medical treatment. Use oxygen exactly as prescribed by your child's healthcare provider. ✔ Oxygen used properly is safe.
Can kids take oxygen?
Your child's doctor and health care team will determine if your child needs additional oxygen in order to keep the right amount of oxygen in the blood. Oxygen is often needed to keep the child comfortable, decrease the amount of work needed to breathe and, in some cases, help your child grow.
Why is oxygen blue?
simultaneous electronic transition occurs to the 1Af state in one molecule and the l2ff+ state in theother. 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.
Is it possible to solidify air?
A pioneering approach developed by IIASA researchers and colleagues proposes solid air (nitrogen or oxygen) as a medium for recycling cooling energy across the hydrogen liquefaction supply chain. At standard temperature and pressure, air is a gas, but under certain conditions, it can become a liquid or solid.
