What will a helium filled balloon do in space?

In space, a helium-filled balloon will expand further due to the lack of air pressure outside the balloon. Eventually, the balloon will burst because the pressure from the helium inside will exceed the pressure outside.


Why do you have to hang onto your helium balloon?

Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.


What happens when a helium-filled balloon is released and rises into the atmosphere?

As the helium-filled balloon rises into the atmosphere, the surrounding air pressure decreases while the pressure inside the balloon remains the same. This causes the helium inside the balloon to expand, making the balloon increase in size. Eventually, the balloon will reach a point where the difference in pressure between the inside and outside of the balloon will be equal, and it will float at that altitude.

What is the answer for it already has helium but what is it?

The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.


What makes a helium balloon?

A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.


Which balloon would fly higher the one with helium or the one with air?
