On the street, the balloons sold in the park are hydrogen or helium, as the question is, that is, fo

The ones sold in the park that can float are hydrogen balloons, and the ones that can be twisted into various shapes are small gas bags, which are air.

Most of the balloons sold on the street are hydrogen balloons.

Because the ** of hydrogen is 1 10 of helium, small traders will not sell helium balloons. To be on the safe side, it is best not to buy it for small children. Because hydrogen is flammable and explosive. What is the gas in the balloon What is the gas in the balloon sold on the street?

If you run out of gas, is there any way to make it fly again? A lot of people say it's not hydrogen. There is no doubt that the balloons sold on the street are filled with hydrogen.

If you use helium, the cost is too high, and it is not easy to prepare, if the gas runs out, then find a balloon seller to help you, there is generally no way to get it at home As long as it can float in the air, it is hydrogen without exception! Therefore, these balloons are very dangerous and violate the express regulations of the state. Because of the cost, almost no vendor will fill the balloon with stable and safe helium.

Because the price of a liter of pure hydrogen is about yuan, and the price of a liter of pure helium is yuan, the difference between the two is about 7 times. The average children's hydrogen balloon is about 3-5 yuan a piece, that is to say, it is impossible to buy a safe helium balloon for less than 20 yuan. Hydrogen is flammable and reacts violently with oxygen to burn when exposed to an open flame in the air.

According to the regulations, it should be filled with helium, which should be inert and non-flammable. However, helium is more expensive than hydrogen, and most small traders will not use this gas, but use hydrogen, a cheap and flammable gas, which is easy to **, and it is recommended not to buy it.

Most of the balloons sold on the street are hydrogen balloons, and helium is a noble gas, inert gas, which is non-flammable; Hydrogen is a flammable gas. A hydrogen balloon is a light bag-shaped or sac-shaped object filled with hydrogen, and an object that can float upwards by the buoyancy of hydrogen is called a hydrogen balloon. Hydrogen balloons include rubber hydrogen balloons, plastic film hydrogen balloons and cloth-coated hydrogen balloons, smaller hydrogen balloons, which are currently mostly used for children's toys or festive releases.

Larger hydrogen balloons are used to float advertising banners, also known as floating hydrogen balloons.

Difference Between Hydrogen Balloon and Helium Balloon.

1. The gas charged is different: the gas filled in the helium balloon is helium, and helium is a kind of rare gas. A hydrogen balloon is a light bag-like or sac-like object filled with hydrogen, with hydrogen being the lightest and having a density of grams per liter.

2. The time of appearance is different: helium balloons really began to be produced at the end of the 70s of the last century. Hydrogen balloonThe world's first hydrogen balloon was born in 1780, when the French chemist Braque poured hydrogen into the bladder of pigs to make the world's first hydrogen balloon.

3. Different uses: Helium balloons can be used as advertising balloons, which is the best gift for major enterprises and companies to advertise their products. It can also be used as a birthday party balloon to create a cheerful, peaceful atmosphere that will delight the guests.

Hydrogen balloons: Smaller hydrogen balloons, currently mostly used for children's toys or festive releases. Larger hydrogen balloons are used to float advertising banners, also called floating hydrogen balloons, which are used to detect high altitudes in meteorology, and used to set up communication antennas or distribute leaflets in the military.

Inside the balloon is hydrogen.

The hydrogen atom is the first in the periodic table, it contains only one proton, the relative molecular weight is the smallest, and the density of hydrogen is the smallest, so injecting hydrogen into the balloon can make the balloon lift off. Balloons can be used not only as toys and decorations, but also as means of transportation, such as hot air balloons.

High-quality balloons are made of environmentally friendly rubber, and after the balloon is blown up, it is exposed to the air, and the degradation begins, and finally it will be like leaves, and it can quickly decompose into the soil without causing environmental pollution.

Precautions for children playing with balloons.

Guarantee the quality of the balloons. When buying balloons for children to play, pay more attention to the quality of the balloons, to ensure that the balloons will not burst easily, otherwise it is easy to frighten the child, which is a very bad thing, so pay more attention, otherwise it will hurt the child, and try to buy high-quality balloons when buying balloons, otherwise it will hurt the child.

Try not to let your child touch sharp objects with a balloon. Balloons are also easy to burst in the process of playing, so parents must pay more attention when playing balloons for their children, and be careful to touch some sharp objects, otherwise it is easy for the balloon to be punctured. Parents should be more careful when children play with balloons.

The answer to the question of whether a balloon is hydrogen or helium is actually very simple, most balloons are filled with helium because helium is very safe than hydrogen. Helium is stable, non-flammable, and is particularly suitable for balloons because it is lighter than air and does not easily penetrate ink to block light. Although hydrogen is more buoyant, it is used in some other fields such as medical and scientific research because it is flammable and unstable.

Expanding on this, the history of balloons is actually very interesting, and its invention is also related to hydrogen and helium. In the late 18th and early 19th centuries, many scientists began to study the properties of gases. In 1783, Lieutenant Montgover of France designed a small ball made of paper and rubber, which was filled with hydrogen, which was the first balloon in history.

However, the disadvantage of hydrogen balloons is obvious: once the fire source hits, the hydrogen will burn, and the passengers will not be spared. This was seriously confirmed in the subsequent Black Friday crash, when all 19 passengers and crew members of the hydrogen balloon were killed during the flight, which also led to public eschatology about hydrogen balloons.

To solve this problem, scientists began to study safer gases, which eventually led to the discovery of helium. Helium is not only safe, but also more stable than hydrogen, and has better buoyancy, so it has become the inflatable material for balloons. Therefore, most of the balloons we use now are helium balloons, and they are very common in various celebrations, item identification and other occasions, and everyone must have seen them often in 1110.

In conclusion, the balloons on the street are helium because helium is safer, more stable, and has good buoyancy than hydrogen. Although hydrogen balloons have applications in some special fields, in everyday 1110, helium balloons are the most widely used inflatable materials. Rent <>
