It doesn't matter how big the balloon is when it floats up.
If it is filled with hydrogen or helium, which is less dense than air, it can float up no matter how big it is.
If it is filled with carbon dioxide, which is denser than air, it cannot float up no matter how small it is.
A balloon is a sealed bag filled with air or some other gas. Balloons can be used not only as toys, but also as a means of transport. There are many types of balloons, now mainly introduce the balloons produced by natural latex, which can be used as decoration, arches made of opening ceremonies, can be printed with their own advertising patterns as publicity, can be printed with photos of the wedding couple as congratulations, can be decorated with balls, newlyweds floats, etc., now balloons have become a beautiful landscape, more and more favored by people!
Balloons used to be called "eggplant" as a toy, and there was a small bamboo whistle at the opening of the balloon, and when the balloon was blown full of air, the mouth would be very loud. Balloons can also be used as decorations and as a means of transport. If the balloon is large enough and the gas inside is lighter than the same volume of air, the buoyancy generated exceeds the weight of the airbag and attached objects (e.g. gondolas, hot air balloons, etc.), the balloon can be raised.
-
It depends on what kind of gas is filled inside, if it is hydrogen, as long as the weight of the balloon skin is light enough, it can fly. If it's carbon dioxide, no amount of balloons will fly.
-
It is generally three times larger than the normal size of the balloon itself.
-
Floating balloons, as long as they are full of hydrogen, they can float up.
-
It's not too small to float.
-
Yes, as long as there is enough hydrogen in it.

The balloon is filled with hydrogen or helium. Since hydrogen and helium are both lighter gases than air, balloons are in the air like wood in water, buoyant upward and gravity downward. When the buoyancy is greater than the gravitational force, the balloon can fly into the sky.
Balloons are usually filled with hydrogen or helium. Hydrogen or helium is much lighter than the same volume of air, so a balloon filled with hydrogen or helium will have more lift. If you hang a big basket under the balloon, you can take people to the sky.
In addition, there is now a hot air balloon that is filled with hot gas. We know that hot air is lighter than cold air, and when the balloon is filled with hot air, it will be buoyant upward by the cold air around it, causing the balloon to rise, and if the heat is controlled, it can stay at different altitudes.
In fact, it happens when the balloon flies to a certain height**. When the balloon rises in the air, the outside air pressure is also changing with the increase in altitude, when the balloon flies higher, the thinner the air will be, the air density will become smaller, and the gas density inside the balloon is relatively larger and larger, so the balloon will slowly expand, when the balloon material can not continue to expand, the balloon will occur, unable to continue to rise.
-
The balloon will float in the air because the gas filled in it is less dense than the air, so it will float upward, but the balloon blown out by people themselves will not float upward, because the proportion of carbon dioxide in the balloon is larger, but when inflating the balloon, hydrogen cannot be used to avoid the occurrence of **, which endangers life safety.
The reason why balloons will float in the air.
1. Introduction to the reasons.
Balloons float in the air because the density of the gas in the balloon is less than that of the air, so that it can float upwards, such as helium, and the balloons that people blow themselves will fall downwards because the balloon contains more carbon dioxide, which is heavier than the air and cannot float upwards.
2. Inflatable method.
In the process of inflating the balloon, you can use a pump to inject air into the balloon, but this kind of balloon can not float into the air, if you want the balloon to float up, you can use helium when pumping, it is best not to use hydrogen, because in the case of hydrogen flame, there will be ** spontaneous combustion, which is prone to fire.
3. Precautions.
The more gas in the balloon, the thinner the surface of the balloon, so when using the balloon, it should not be placed in a place with sharp objects to avoid the balloon being punctured, and the balloon residue that has been ruptured should be cleaned up in time to avoid children from ingestion and suffocation.

The gas that floats in the balloon is hydrogen.
At room temperature and pressure, hydrogen is a highly flammable, colorless, transparent, odorless and tasteless gas. Hydrogen is the least dense gas known in the world, and its density is only one-fourteenth that of air, i.e. at 0 degrees Celsius, at one standard atmosphere, the density of hydrogen is grams per liter. Therefore, hydrogen annihilation gas can be used as a filling gas for airships and hydrogen balloons.
Hydrogen is the substance with the smallest relative molecular mass and is mainly used as a reducing agent.
Hydrogen was first produced artificially in the early 16th century by placing the metal in a strong acid. 1766 In 1781, Henri Cavendish discovered the element of hydrogen in the acre, which was burned to produce rapidly changing water, which Lavoisier named "hydrogenium" based on this property. In the 50s of the 19th century, when the British doctor Hexin wrote the "New Edition of Naturalism", he put it"hydrogen"Translated as "light gas", it means the lightest gas.

According to the formula of air density and balloon buoyancy, you can calculate how big a floating balloon needs to carry 10 grams of objects. Buoyancy is generated by the air being expelled, and with the density of air and the volume of the object v, the buoyancy f can be expressed as:
f = vρg
where g is the acceleration due to gravity, and g is approximately equal to m s on Earth.
Assuming that the density of the air balloon is 100 times smaller than that of the air, that is, the density of the air balloon is kg m, and the density of the object is greater than that of the air, which can be ignored, assuming that the air balloon can reach the maximum expansion state, then we can calculate how big the air balloon needs to be by calculating the volume of the air balloon to carry 10 grams of object, and the calculation formula is as follows:
v = f g) = 10 cm Therefore, it takes about cubic centimeters of floating acres of balloons to pick up 10 grams of objects. It is important to note that this result is only an estimate, and the actual situation is also affected by factors such as the mass of the balloon, the shape and size of the object, etc.

To calculate how big an object a balloon is capable of carrying, one needs to consider the buoyancy of the balloon and the mass of the object. Buoyancy refers to the upward thrust experienced by an object in a liquid or gas, i.e., the Archimedes force. If the gravitational force of an object is greater than the buoyant force, it sinks.
If the gravitational force of an object is less than the buoyant force, it will rise. Balloons use the principle of buoyancy to fly.
The buoyancy of a balloon depends on the volume of the balloon and the density of the gas filled in the balloon. The less dense the gas filled in the balloon, the greater the buoyancy. Therefore, helium is more suitable for use in balloons than air.
Let's say we have a balloon that can hold 1 cubic meter of helium. Depending on the density of helium, the mass of 1 cubic meter of helium is about grams. Thus, the buoyancy of this balloon is about 1 kilogram (1000 grams) of an object.
If we want to know how big an object this beam balloon can carry, we need to consider the weight of the object. Assuming we want to know that this balloon can carry up to 10 grams of objects, we can use the following calculation:
The weight of a 10-gram object is about kilograms (10 grams divided by 1000). Therefore, we need to find an object that is lighter than a kilogram to ensure that this balloon can carry an object of 10 grams.
According to the above calculations, this balloon can carry up to 1 kg of objects. Thus, this balloon can carry an object of 10 grams, as well as an object of 100 grams, an object of 1 kilogram, or even heavier. Limb irritation.
It is important to note that this calculation is only an approximation. The size, shape, material, and density of the gas all affect the buoyancy of the balloon. In addition, the buoyancy of balloons will vary at different altitudes and temperatures.
Therefore, if it is necessary to accurately calculate how large an object a balloon can carry, more complex calculations and experiments are required.

To pick up a 10-gram object, a floating balloon needs to provide at least 10 grams of upward buoyancy. According to Archimedes' principle, the buoyant force experienced by an object is equal to the weight of the liquid (or gas) it expells. Therefore, to calculate how much buoyancy a balloon can provide, it is necessary to know the volume of its hand and the density of the gas it contains.
Suppose the volume of the balloon is 1 liter (about 1000 cubic centimeters of bidenier), the gas contained is helium, and its density is grams. Therefore, the buoyancy provided by this balloon is grams liters x 1 liter = grams.
The buoyancy provided by this balloon is not enough to carry a 10-gram object as it provides only grams. To pick up a 10-gram object, a buoyancy of at least 10 grams needs to be provided. Therefore, a larger balloon or a lighter gas, such as hydrogen, which has a density of grams, is about half lighter than helium.
It is important to note that if the balloon is too large, it will not be able to stay in the air due to its own weight. Moreover, hydrogen is a flammable gas and requires appropriate safety measures. To ensure safety, it is best to use professional balloons and gases, or consult professional advice.

This question relates to the principle of buoyancy in physics. Buoyancy refers to the upward force experienced by an object when it is immersed in a liquid or gas, and its magnitude is equal to the weight of the liquid or gas that is discharged. An air balloon is a gas-filled sphere whose buoyancy is equal to the weight of the air it explodes.
Therefore, if you want the balloon to be able to carry up to 10 grams, you need to make sure that the buoyancy of the balloon is greater than or equal to the gravitational force of the object. Assuming that the gravitational force of this object is 10n, then the buoyancy of the air balloon must be greater than or equal to 10n to bring up this object.
According to the buoyancy principle, the buoyancy of the air balloon is equal to the weight of the air discharged, which can be calculated by Tongbi by the following formula:
Buoyancy = weight of the air expelled, = density of the air, volume of the expelled.
Therefore, as long as the volume of the balloon is large enough, it can generate enough buoyancy to carry up a 10-gram object. The specific size needs to be calculated according to factors such as the density of the air balloon material and the air pressure and temperature of the environment.

According to Archimedes' principle, when an object is immersed in a liquid or gas, it is subjected to an upward buoyant force equal to the weight of the liquid or gas that the object is discharging from the Sakura. Therefore, we can determine how big an object the balloon is capable of carrying by calculating the weight of the gas expelled.
Suppose we have a balloon that can carry 10 grams of objects, we can first fill the balloon with helium or hydrogen so that the balloon will float in the air. Then, we can weigh the imitation clump balloon, put another 10 grams of object on the balloon, and weigh the balloon again. At this point, we can calculate the weight of the gas that the balloon will expel to determine the maximum weight that the balloon can carry.
The specific calculation formula is as follows:
Buoyancy = Weight of the gas discharged = Balloon weight + Object weight - The total weight of the balloon and the object.
Assuming that our balloon weighs 2 grams, the object weighs 10 grams, and the total weight of the balloon and object is 12 grams, then we can come up with the following calculation:
Buoyancy = 12 grams - 2 grams = 10 grams.
This means that our balloons can carry a maximum weight of 10 grams of gas, and a maximum weight of 10 grams. If we want a balloon to carry a heavier object, we need to use a larger balloon or lighter gas to fill the balloon.

Summary. A normal balloon can be propelled with gas or air currents, thus making it float. You can blow into the balloon with a hair dryer or blowpipe to fill it with gas, and then the balloon can float up.
You can also use the wind to place the balloon at the tuyere, and the balloon can float up due to the action of the air current.
A normal balloon can be propelled with gas or air currents, thus making it float. You can use a hair dryer or blowpipe to blow into the balloon to fill it with gas parsley, and then the balloon is ready to float. You can also use the power of the wind to place the balloon at the tuyere, and due to the effect of the air current, the balloon can float up.
Fellow, I really didn't understand, I can be more specific.
The principle of ordinary balloon float is that the air inside the balloon is lighter than the air outside, so the balloon will be pushed upward by the flow of air in the outer grinding part. If you want to make the balloon float, you need to fill the balloon first, and then put the balloon into an air flow environment, such as tuyere, fan, etc., to make the balloon float hole.

1.The balloon will get bigger.
When the balloon rises, the atmospheric pressure at high altitude is very small, if the volume of the balloon does not change, the internal pressure will not change, the internal pressure will not change, the external pressure will become smaller, it will inevitably not be balanced, and the balloon will inevitably become larger.
2.When the balloon is bigger, the pressure is smaller, and the gas satisfies the equation of state PV=NRT, and under the condition that the number of moles n, the constant r, and the temperature t are all unchanged, the volume is large, and the pressure is of course smaller.
3.Balloon rises, buoyancy is how to change, although the volume is large, but the air is thinner, the density is small, the specific change of buoyancy is greatly affected by weather and regional differences, with the actual situation is different, in general, the buoyancy gradually decreases, and eventually may be suspended in the air, but in fact, because the elasticity of the balloon will hinder the balloon from becoming larger, and there is a certain tolerance limit to the pressure difference between inside and outside, generally has not reached the height that can be suspended, because the elasticity of the balloon knows how to limit the volumeThe volume of the balloon can no longer be larger, and the internal pressure can not change, which means that the balloon continues to rise, the external pressure continues to decrease, and the pressure difference between the inside and outside increases, and the bearing capacity of the balloon will burst.
A 30mm*40mm photo is equivalent to a 12-inch x 16-inch photo, so a 30mm 40mm photo should be counted as a two-inch smaller photo. According to the standard specifications, the size of a 1-inch photo is 25mm 30mm, and the size of a 2-inch photo is 35mm 49mm, so 30mm and 40mm should be counted as two inches.
