What will happen when a lid of a jar of helium is removed?

The bottle will just feel like a bottle full of air. In order for it to float like a balloon filled with helium, it would have to weigh less than air or you would need to fill the bottle to well over its capacity. 1 cubic meter of helium is required to lift 1kg.


Why do balloons decrease in size after a while?

Why does a balloon go down after a few days?A balloon goes down after a few days because the helium can pass through the skin of a balloon which then reduces the size of the balloon and the balloon then slowly reaches the floor after loosing all its helium.If you need any more help visit www.wikipidia.comThey loose air somehow.


How many cubic inches of helium does it take to lift 500lbs?

Let's assume you are talking about filling a balloon with helium and using it to lift a 500 pound weight. Unfortunately, there are more factors you need to consider before you can have this question resolved. You need to know the atmospheric temperature, the density of the outside air, the temperature of the helium you're using, and the starting point in relation to the Earth's center of gravity. Also, are you including the weight of the balloon and the rest of your apparatus in the 500 pound figure, if not you need to allow for that. In other words, if you are starting from the top of Everest at 30 below zero, the amount of helium you'll need varies greatly from that of a balloon starting in Death Valley at 120 degrees.


Why does a balloon filled with helium rise while a balloon filled with an equal volume of average atmosphere air does not?

The effect is a result of the difference between the density of the gas within the balloon and the density of the gas outwith the balloon, such that a buoyant force is created that can overcome the gravitational forces upon the balloon. To create a buoyant force, the gas within the balloon must be less dense than the gas outwith the balloon. The gas outwith a balloon is air (atmosphere) which roughly contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Helium is less dense than this combination of gasses, thus if we release helium into the atmosphere, it automatically rises through the atmosphere. Although gravity has an effect upon this gas, the buoyant force can easily overcome it. It will continue to rise until the density of the surrounding gasses is equalised at which point it will hover, neither rising nor falling to any significant degree. A balloon makes use of this buoyant force by trapping the lighter gas within its envelope. Although the weight of the balloon itself adds a greater gravitational force, the buoyant force of the gas within can easily overcome this. If nothing else, this demonstrates just how weak gravity really is -- even a noble gas can easily overcome it! We can achieve the same thing with air itself. Hot air is less dense than cold air (hot air rises, after all), thus if we can heat up enough air within an envelope we can make the envelope rise upwards. Since heat will be lost through the envelope, we must ensure a constant supply of hot air is provided. Thus the balloon needs to be sufficiently large enough to accommodate enough hot air to lift both the envelope and the burner that heats the air. Chinese lanterns are a classic example of this type of hot air balloon. In order to lift people and other objects, we simply need a much larger envelope. Manned hot-air balloons are simply extremely large Chinese lanterns, using propane gas burners to heat the air in the envelope. The materials used in the balloon obviously need to be as light as possible, hence the envelope is constructed from ripstop nylon or dacron, while the gondola or basket is typically made from woven wicker. The burner and propane gas bottles are the heaviest elements, besides the people being carried. The combined weight of a 5-passenger hot air balloon can still be more than 3.5 tons. Even so, 100,000 cubic feet of hot air (weighing almost 6000 lbs) is enough to lift this enormous weight.


How do you make your voice high pitched with helium balloons?

you breath in the helium (you need to breath it in with out letting it out) and then talk.

Where to find helium atoms to make a balloon float?

you can use alpha particles from a cyclotron to get helium nucleuses, then you need to get some electrons from a cathode ray tube, and then you need to put the electrons around the nucleus. This is the most tedious part.


How do you make a balloon float again?

There are a few things you can do to help increase float time. First, be sure to tie a tight knot in the neck of the balloon. The balloons included in Balloon Time have extra-long necks for easier tying. If you are attaching ribbons to the balloons, be sure to tie the ribbon below the knot. For special occasions that require prolonged float time, you can also purchase and add ULTRA HI-FLOAT® product to your Balloon Time balloons.


Could you use helium to float an item into space?

No, air pressure increases as the balloon goes up, so the balloon will pop and fall to the ground. You can get high up in the atmosphere (but you need a LOT of helium and a balloon that can get VERY big) you will not reach "outer" space beyond the Earth's atmosphere.


Why does a balloon need hot air?

Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.

What is the weight of water displaced by a massless balloon?

No real object is massless. Even a balloon has the mass of the balloon plus the mass of the entrained gas.But if the buoyancy of the entrained gas (hydrogen, helium) allows the balloon to float away, then it will displace no water. Even so, it still has mass.

Does a hot air balloon need heat or cold air to float?

hot


Can you fill helium balloons with normal air?

No it doesn't have helium. A hot air balloon derives it's lift from heated air, which is less dense and therefore lighter than normal air. A helium balloon derives it's lift from helium, a gas which at normal temperatures is less dense than normal air. So both fly 'lighter than air' but for different reasons.


What volume of helium in a balloon half a mm thick?

You will need to know the actual size of the balloon as the bigger its inflated the more gas volume required.


What is the difference between a helium balloon and a hot-air balloon?

A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
