# Gas balloon physics.

## Recommended Posts

Practically, How much we can inflate a gas balloon i.e fill it up with gas ?

Why after a certain air is filled in Balloon the Balloon bursts ?

Can we measure helium or hydrogen gas filled in Balloon ?

I mean weight of the gas in the inflated balloon?

If yes, how?

If no, why?

Thanks & Regards,

Prashant S Akerkar

All the way.

All the way + even a tiny bit more = burst.

We can, yes. Those dispensing such gases can, yes. Those with an understanding of search engines can look it up, yes.

You can't, no.

Because you don't seem to be able to do research on simple science. This site is best used for science discussion, not asking to be taught science. Discussion is different than lecturing or teaching. Questions are wonderful, but it looks like you're using us to do research for you, instead of trying to learn science more deeply through conversation.

Mass of the gas in the inflated balloon:

You need to know:

1. weight of balloon empty

2. pressure of gas when full

3. Volume of gas when full (volume of balloon)

4. Ambient air temperature, pressure and relative humidity (to give you air density of displaced air, you can google this as Phi suggests)

5. weight of balloon full/or force required to stop it lifting skyward

6. Some equations (google again) and some math
