Answer and Explanation:

There are metal tanks that hold oxygen gas for people to breathe when they swim underwater for a long time. They are shaped like a cylinder. The oxygen gas in these tanks moves around and forms the same cylinder shape as the tank. ... Then the gas inside the balloon will change shape, too.

Answer:

Because helium is a lot lighter than air, and helium is less dense than air even when the helium has the same temperature as the surrounding air.

A helium- filled balloon doesn't need to warmed up in order to rise.
