What Causes a Balloon to Expand in Space?

In summary, the conversation discusses suspending a ball in a tank of water and the effect of taking the system into space. The volume of the balloon increases due to the decrease in air pressure in the balloon. The air pressure inside the balloon is equal to the outside when on the ground, but decreases when taken into space. The balloon expands due to the decrease in air pressure.

we suspend this ball in the tank by using a string ,then filling the tank with water as shown..
thus we have,
Fb=Ft+Fg(I guess so)

what happens when this tank with its contents is transported to the space

The volume of the balloon increases so why?

Presumably, you mean "transported to orbit or beyond". What is different for the tank and balloon (and everything else) when not on Earth?

the acceleration due to gravity.

could you tell me why the volume of the ballom increases on going to space?what is the effect of acceleration due to gravity on the volume of the ballon?

You have stated, correctly, that the balloon would expand if the system is taken to space. What is it that keeps the baloon from expanding when the system is on the ground?

the air pressure is equal inside the balloon and outside the balloon correct?

Yep. So what happens to the air pressure then you take the system out of the atmosphere?

the air pressure inside the balloon becomes less,correct?

yes, but why? What happens to the balloon?
 
  • #9
Wouldn't the pressure inside the balloon stay constant assuming no leakage?

What HAPPENS to the balloon? Does it shrink? Get bigger? Stay the same?

Ah, sorry :)
 

FAQ: What Causes a Balloon to Expand in Space?

What is a suspended balloon in space?

A suspended balloon in space is a balloon that is kept in place by some force, such as gravity or electromagnetic forces, without touching any surface. This means that the balloon is not resting on anything and is instead floating freely in space.

How does a suspended balloon in space stay in place?

A suspended balloon in space stays in place due to a combination of forces acting on it. For example, if the balloon is filled with helium, it will rise due to the buoyant force. Gravity will also play a role in keeping the balloon in a stable position.

What is the purpose of a suspended balloon in space?

The purpose of a suspended balloon in space can vary depending on the specific situation. It can be used for scientific experiments, as a form of transportation, or for observation purposes. It can also be used to study the effects of microgravity on objects.

How is a suspended balloon in space different from a regular balloon on Earth?

A suspended balloon in space is different from a regular balloon on Earth in several ways. Firstly, a regular balloon on Earth is affected by gravity and will eventually fall to the ground. In contrast, a suspended balloon in space is not affected by gravity in the same way. Additionally, the atmospheric conditions in space are very different from those on Earth, which can affect the behavior of the balloon.

What challenges are associated with a suspended balloon in space?

There are several challenges associated with a suspended balloon in space. One major challenge is maintaining the balloon's position and stability in the often unpredictable environment of space. Another challenge is ensuring that the balloon does not come into contact with any potentially damaging objects or debris. Additionally, maintaining the balloon's inflation and structural integrity can also be challenging in the harsh conditions of space.
