Some scientists believe that helium should not be used to inflate party balloons. why

Why is helium gas used to fill balloons instead of hydrogen gas? In order to get a floating balloon you want a gas which is as light as possible. Helium is quite a lot lighter than air weight. ... You'd have thought that hydrogen would be a better gas as it would give slightly more lift than helium because it's lighter.

Explanation:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
