Can solid diffuse in air?
Some solids diffuse in liquids but not in gasses, some solids diffuse in gasses but not in liquids.
Is air made up of solid?
It's important to understand, though, that the air itself is /not/ made of solids. The oxygen, nitrogen, carbon dioxide, etc. that make up most of the air are very definitely gases (this means that the molecules of these things are not stuck together).
What is solid air made of?
Composition of Dry Air – The Data
| The numbers below are averages. In modern times, the percentage of carbon dioxide in air has been rising with the burning of fossil fuels. Methane has also risen significantly. | |
|---|---|
| Nitrogen | 78.08% |
| Hydrogen | 0.000055% |
| Nitrous Oxide | 0.000032% |
| Carbon Monoxide | 0.00002% |
What is floating in the air that we breathe?
The air is composed of gases (oxygen, carbon dioxide, nitrogen), airborne microorganisms, and dust, but it also contains a multitude of very tiny chemical compounds that are like floating food for airborne microorganisms.
How do solids diffuse?
Diffusion can take place in gases, liquids, or solids. In solids, particularly, diffusion occurs due to thermally-activated random motion of atoms – unless the material is at absolute zero temperature (zero Kelvin), individual atoms keep vibrating and eventually move within the material.
What is solid solid diffusion?
Diffusion in Solids Diffusion refers to the transport of atoms in a medium along a given direction, It takes place in solid liquid or gas. It occurs even in the absence of any external force.
Where does the air come from?

Can air be frozen solid?
Yes, air can freeze. Air is composed of 21% oxtgen, 78% nitrogen, and 1% argon (roughly, since trace gases like carbon dioxide and water vapor can also be in air). Oxygen freezes at -360.9 °F, nitrogen at -346.18 °F, and argon at -308.7 °F. Therefore, air will freeze if it gets cold enough to freeze oxygen.
What is solid air called?
aerogel. (redirected from Solid Air)
Do we breathe out our food?
The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbohydrates, fat and proteins we consume and digest are eventually converted by a number of different biochemical pathways in the body to glucose (C6H12O6).
Why do we never run out of oxygen?
Yes, sadly, the Earth will eventually run out of oxygen — but not for a long time. According to New Scientist, oxygen comprises about 21 percent of Earth's atmosphere. That robust concentration allows for large and complex organisms to live and thrive on our planet.
Why can diffusion happen in solids?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, as the atoms in a solid are stationary (they vibrate in a regular arrangement due to being the state with the least energy), the particles cannot move and therefore cannot diffuse.
What are examples of diffusion of solids in solids?
The chowk powder spreads on black board suface and settle down, the air dust spreads and settle on our household objects or on any objects, spreading of powder on ourself body etc all are examples of solid-solid diffusion.
Can solid particles be diffused?
Diffusion can happen in solids as well. Solid-state diffusion is an extremely slow process. Solid particles have the lowest kinetic energy and so do not move.
Why can diffusion occur in solids?
The particles must be able to move around for diffusion to work. Diffusion does not occur in solids because the particles in a solid can only vibrate and cannot migrate from one location to another.
Do trees make air?
Here is the super hero part. Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

Can you make liquid air?

Can a person live after being frozen?
Cryonics procedures may begin within minutes of death, and use cryoprotectants to prevent ice formation during cryopreservation. It is, however, not possible for a corpse to be reanimated after undergoing vitrification, as this causes damage to the brain including its neural circuits.
Can we eat solid oxygen?
1. Solid oxygen sublimes to gaseous oxygen at -218 degree Celsius. 2. So, it is not practically possible to eat solid oxygen as it is not stable in its solid form at the temperatures upto which human can survive.
Can oxygen form in solid?
Solid oxygen is not only metallic under pressure, but actually becomes a superconductor near 100 giga-pascals5 (GPa). At low pressures, solid oxygen is an insulator. With increasing pressure, oxygen crystallizes into a sequence of different crystal structures.
Can you eat air?
You get aerophagia when you swallow so much air that it makes your stomach feel bloated and uncomfortable. Chewing gum can make it worse. Doctors often see aerophagia as a sign of other problems, such as an illness that affects your digestive system, or a psychological disorder like anxiety or depression.
Should you breathe while you chew?
But to eat, you need to breathe. Chewing and digesting food — like anything else you do with your body — use oxygen. That means you need to work harder to breathe in enough of it while you eat.
What will happen if Earth loses oxygen for 5 seconds?
If the world lost its oxygen for five seconds, the earth would be an extremely dangerous place to live in. Due to the severe sunburn, our inner ear would explode. The air pressure on the earth would drop 21 per cent and our ears would not get enough time to settle.
Is Earth losing its oxygen?
It sounds worse than it is: Earth's atmosphere is steadily losing oxygen. But before you panic and gasp for breath, understand that oxygen levels have only dropped by 0.7 percent over the past 800,000 years. So you don't have to worry about widespread asphyxiation just yet.
Do trees pee?
Trees also excrete water vapour containing various other waste products during this process. While this is an excretion, you may not consider this akin to pooping and peeing, perhaps more like breathing. After all, humans expel carbon dioxide, water vapour and certain other substances while breathing.
Do trees feel pain?
Do plants feel pain? Short answer: no. Plants have no brain or central nervous system, which means they can't feel anything.
What is the only thing the earth needed?
The only thing the earth needed was a downpour or at least a shower. Throughout the morning Lencho — who knew his fields intimately — had done nothing else but see the sky towards the north-east.

Can oxygen be a solid?
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.
