How much does an 8 foot weather balloon lift?

How much can a helium balloon lift?

depends how big the helium balloon is and how many

How much hot air does it take to raise a hot air balloon?

No set answer to that, it depends on how much the balloon has to lift.

How will you measure the buoyant force of a balloon?

Measure how much it can lift.

Why is the weather balloon drawn so tall and thin?

To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.

What does weather balloon cost so much?

because the hulium itself cost more that the balloon so its the hulium that made the balloon to cost so much plus all the other stuff.

How much weight will a helium balloon carry?

You measure the circumference of the balloon which is 46.75 and one cubic foot of hellium and it lifts about 1 ounce of sugar/anything, So one cubic foot of hellium will lift 1 ounce.

How do weather balloons make weather measurements?

A Weather Balloon is attached to an instrument called a Radiosonde. The radiosonde is a a box with smaller instruments to measure the temperature, dew point, wind speed, and wind direction, among other things, at different levels of the atmosphere. The balloon pretty much is there to lift the Radiosonde through the atmosphere.

How much flotation does a cubic foot of air have?

Everything I can find says that a cubic foot of air can lift about 62-63 lbs.

How far can a weather balloon travel in the atmosphere?

It depends on the wind and balloon payload. The smaller the payload, the higher the balloon may rise before it bursts. The balloon I helped launch landed close to 60 miles from the launch site.

Which gas inflates a balloon the longest carbon dioxide or helium and why?

Carbon dioxide will keep a balloon inflated longer than helium will, because its molecules are much larger and therefore less able to escape through the material of which the balloon is made.On the other hand, helium is much lighter so will give a balloon greater lift while it lasts.

Why are weather balloons partially infated before they're released into the atmosphere?

As you rise in elevation, the pressure around you decreases. This lower pressure would cause the balloon to expand, and burst if it was inflated to much originally. By starting it off only partly filled, it will expand to a normal size and not explode.

A balloon floats motionless in the air. A balloonist begins climbing the supporting cable. In which direction does the balloon move as the balloonist climbs?

The balloon will move down as the balloonist transfers his weight onto the cable. If the balloon has enough bouyancy in air, enough lift, it will return back up to the position it was when our climber approached the support cable. This assumes the balloon is tethered to the ground and has just a bit more lift than the opposing mass of the balloon and the climber. The balloon will have lifted the balloonist up along with its own bulk. As the climber climbs, the balloon might experience the slightest "dip" at each transfer of the balloonists weight as he moves up the cable, unless he moves very slowly. Again, this is for a balloon capable of lifting itself and the balloonist, but which only has a bit more bouyancy in air than the total load on it. That means it can barely lift itself and the balloonist. If the balloon was at equilibrium as far as its lift where it was just able to support the weight of its own bulk, the balloonist will be pulling it down as he climbs and will remain near the ground while pulling the balloon down toward him with each step of his climb. The climber has added "too much weight" to the craft. In the end, he will have pulled the balloon down to himself on the ground. In the case of a really big balloon with a huge amount of lift that was tethered to the ground, it would hardly move at all, but would move down a tiny bit as the climber began, and then pretty much stay put in the air as the climber mounted the support cable.
