Why don't normal balloons stay in the sky?
Due to the weight of the balloon. A balloon is merely a capsule full of air so it will fall to the ground as the balloon weighs it down. A helium balloon will rise into the air because helium is less dense than normal air (i.e. it weighs less). The air inside the balloon is the same density as the air outside. The balloon material itself is heavier than air, which causes the balloon to sink. If you decrease the density of the trapped air, such as by heating it or replacing it with hydrogen or helium, the balloon may become even lighter than the balloon material and an equal volume of normal air, in which case the balloon will float or rise.
Why does an argon balloon sink?
Because it is heavier than air.
Do objects get heavier or lighter when heated?
Heating things up causes them to expand. As a result, a hot air balloon floats because the envelope containing the air (the balloon) has less air in it then the air outside the balloon at a lower temperature. This might be what you're thinking about.
How do you make a balloon rise?
Instead of blowing normal air (your breath, a pump, etc.) into the balloon, you'd use helium to make it float.
Why is a balloon heavier when it is blown up with air?
This depends on whether you consider what is inside the balloon to be a part of the balloon, since the weight of the balloon skin will remain the same regardless of what is inside it. If, however, you consider the contents of the balloon to constitute a part of the balloon's mass then it will always be heavier when inflated, regardless of the density of the substance with which it is inflated. However, in this case the density of the balloon will fall when inflated if the contents are less dense than the material of the balloon, which is highly likely since the substance would probably be a gas. Therefore the balloon would be heavier but less dense.
How does a air balloon fly?
air is heavier than balloon, air rises
How does air make a balloon fly?
air is heavier than balloon, air rises
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
Does air pressure tell you how heavy air is?
Yes because when when you put a balloon in the air the balloon will tell you if its heavier or lighter.

Because it is heavier than air.
Is an air inside a balloon a pure substance?
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
Is cfc heavier than air?
Yes CFC's are much heavier than air. If you filled a balloon with CFC's, it would drop, not float away.
Why can't a hot air balloon go to any of the other layers of the atmosphere?
because the air inside the balloon is heavier than the air outside in the other layers of the atmosphere
Why does'nt a balloon with carbon dioxide float and a balloon with helium does?
Because, carbon dioxide is heavier than air whereas helium is lighter than air.
Can dry ice float a hot air balloon?
No. Dry ice is frozen carbon dioxide, which is heavier than air, so wont float a balloon.
Once an airballon is in the air what happends to the air in the balloon?
If you mean a kid's balloon, nothing. If you mean a hot air balloon, then it slowly cools and thus gets denser (heavier). Therefore it needs to be re-heated periodically.
