# The suspended ballon in space

[PLAIN]http://img521.imageshack.us/img521/7651/unled1234.jpg [Broken]

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 ballon 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 ballon and outside the ballon correct?

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

the air pressure inside the ballon becomes less,correct?

yes, but why? What happens to the balloon?

Wouldn't the pressure inside the balloon stay constant assuming no leakage?
