A balloon is an object that hovers and move with the wind.
Well...it's because they're not the same balloons. There is a product out there called Super Hi-Float. You coat the inside of a balloon destined to be filled with helium with it, and it helps seal the pores of the latex hence holding the helium in longer. You probably wouldn't do this with a balloon you're going to fill with CO2.
Yes.
No, the density is too high.
Helium gas is lighter than air and hence balloons filled with helium will float in air.
First, the balloon would float to the ground. After that, nothing special happens to the balloon because you filled it with oxygen.

There are a few things you can do to help increase float time. First, be sure to tie a tight knot in the neck of the balloon. The balloons included in Balloon Time have extra-long necks for easier tying. If you are attaching ribbons to the balloons, be sure to tie the ribbon below the knot. For special occasions that require prolonged float time, you can also purchase and add ULTRA HI-FLOAT® product to your Balloon Time balloons.
Fill a balloon part way with helium, make an animal out of it and have it float.
The key word there is float. There is nothing in space for a hot air balloon to float on.
yes
Heilum combined with the light material of the balloon make it as light as air making it float.
The balloon will either float or pop
Helium goes into a balloon to make it float.
because helium has less density
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
gas
Helium!
