Why is hydrogen so explosive?
Hydrogen gas is very flammable.
The heat given off by the candle provides the activation energy required for the reaction that produces water from hydrogen and oxygen.
This reaction is highly exothermic, producing the prodigious explosion..
How cold is liquid helium?
The primary reason to use liquid helium is that it is cold. Super cold. At normal atmospheric pressure, liquid helium boils at at temperature of just 4.2 Kelvins (-452.11 Fahrenheit).
Which gas is obtained first when liquid air boils up?
OxygenOxygen has the highest boiling point so it forms the liquid first as the air is cooled.
Can liquid hydrogen kill you?
Liquid hydrogen wouldn’t be as reactive, but it the extreme cold and rapid expansion would do a lot of damage, and I’d guess it would be at least as deadly as drinking liquid nitrogen.
Can liquid hydrogen explode?
Even small amounts of liquid hydrogen can be explosive when combined with air, and only a small amount of energy is required to ignite it. Both its explosiveness and the extremely low temperatures involved make handling it safely a challenge.
Why Liquid oxygen is dangerous?
Liquid oxygen is an extremely concentrated substance. While it is not flammable, it accelerates combustion. … Liquid oxygen is especially dangerous when it comes in contact with organic substances. The chances of an explosion are high if liquid oxygen spills on asphalt.
What happens if you touch liquid oxygen?
Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid oxygen.
Does hydrogen explode in air?
Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud.
Is liquid air a pure substance?
A substance that has a fixed chemical composition throughout is called a pure substance such as water, air, and nitrogen. A pure substance does not have to be of a single element or compound.
What is the liquid that comes out of canned air?
refrigerantMost duster contain refrigerant that is liquid when held under pressure. The goal of duster is to spray the vapor not the liquid, so the valving is designed to capture the vapor from the top of the can. When you shake a can, turn it, or flip it upside-down, you can introduce the liquid refrigerant to the mix.
Does compressed air freeze?
When this happens, your compressed air system may sustain both short-term and long-lasting damage. This happens because compressed air systems generate condensate, which can freeze — clogging or even cracking vulnerable air compressor components.
Can you liquify air?
Liquefied Air Air consists of approximately 78% nitrogen and 21% oxygen, and thus has similar thermodynamics properties as nitrogen gas. Liquefied air is produced cryogenically, at -196°C, which is the boiling point of nitrogen; at atmospheric pressure. Liquefying air reduces the volume of air by 700 times.
Is liquid hydrogen safe to drink?
Hydrogen water is generally recognized as safe (GRAS) by the FDA, meaning that it’s approved for human consumption and not known to cause harm. However, you should be aware that there’s currently no industry-wide standard on the amount of hydrogen that can be added to water. As a result, concentrations can vary widely.
How dangerous is liquid hydrogen?
When liquid hydrogen is stored in tanks, it’s relatively safe, but if it escapes there are associated hazards. Topping the list of concerns is hydrogen burns. In the presence of an oxidizer — oxygen is a good one — hydrogen can catch fire, sometimes explosively, and it burns more easily than gasoline does.
What happens if we drink liquid oxygen?
Don’t do it, it is not just hooey it is dangerous. Liquid O2 is a cryogenic liquid, it is used to rapidly freeze things like human tissue. It has a boiling point of -297 degrees. … As mentioned, true liquid oxygen would likely kill you pretty quickly if you tried to drink it.
What temp does air freeze?
32 °Ffreezing occurs when the temperature of air falls below the freezing point of water (0 °C, 32 °F, 273.15 K). This is usually measured at the height of 1.2 m above the ground surface.
Is air a gas or liquid?
Under normal conditions, matter exists as either a solid, a liquid, or a gas. Air is a gas.
Is it OK to gargle with hydrogen peroxide?
Gargling hydrogen peroxide may be an effective way to sooth a sore throat, disinfect your mouth, and whiten your teeth. Just make sure you dilute it first, and try not to swallow any in the process. If you’re hoping to whiten your teeth, try to gargle consistently for several months for the best results.
Can you get liquid hydrogen?
Hydrogen turns into a liquid when it is cooled to a temperature below -252,87 °C. At -252.87°C and 1.013 bar, liquid hydrogen has a density of close to 71 kg/m3. At this pressure, 5 kg of hydrogen can be stored in a 75-liter tank.
Is Liquid Air dangerous?
The liquid inside canned air can cause frostbite when the skin is exposed to a steady stream. This can vary from an intense burning sensation to serious physical injuries such as skin cracking, and damage to muscles, blood vessels and nerves. Asphyxiation and toxicity.
Is Liquid Oxygen good for you?
Supplemental oxygen has shown to be beneficial for many people with chronic lung disease by improving exercise tolerance and breathlessness during exertion. Liquid oxygen, also called LOX, is different from concentrated, or “regular” oxygen.
At what PSI does air become liquid?
60 psigAir is fed at high pressure (>60 psig, or 520 kPa) into the lower column, in which it is separated into pure nitrogen and oxygen-rich liquid.
Can u freeze air?
Yes, you can freeze air, and yes, each ingredient of air will freeze at a different temperature, so that if you were to take a jar of air and slowly make it colder and colder, each different ingredient would freeze into a different layer, just as you suggest.
What is the coldest liquid?
Liquid heliumLiquid helium has a boiling point of -452 degrees F below zero; it is the coldest material known. It is also the only material on earth that never exists as a solid, only as a cryogenic liquid and as a gas.
Is liquid hydrogen expensive?
As of 2019 almost all hydrogen production is from fossil fuels, and emits 830 million tonnes of carbon dioxide per year. … As of 2002, most hydrogen is produced on site and the cost is approximately $0.70/kg and, if not produced on site, the cost of liquid hydrogen is about $2.20/kg to $3.08/kg.
At what temperature does oxygen become a liquid?
For example, liquid oxygen is widely used because it is a good oxidizer for a number of fuels (giving high flame temperature and low molecular mass) and because it is reasonably dense and relatively inexpensive. It is liquid only below −183 °C (−297 °F), which somewhat limits…
