For the same reason that a beach ball can rise high in the water but can't leave the water. A balloon is floating in air. If there is no air around it, then it has nothing to float in.
No. The atmosphere of Mars is too thin.
NASA is thinking it can.
No, the Moon has no atmosphere. The hot air does not have the colder air to be lighter than! Such a balloon would work on Mars or some moons of the larger planets which have some kind of an atmosphere.
Free Atmosphere or Free Air is a part of the atmosphere that lies above the Earths frictional influence.
a hot air balloon only works using thermals, which are currents of hot air rising because one area is heated more than the others. so hot air balloons depend on air to keep it airborne, specifically hot air. once it leaves the earths atmosphere, it is a vacuum. there is no air, so the hot air balloon will fall back into the earth. hence, we see that hot air balloons cannot leave the earth's atmosphere.

air
air
because the air inside the balloon is heavier than the air outside in the other layers of the atmosphere
I do not mean to sound rude or patronising but air IS the atmosphere.

The air particles in the balloon compress due to the cold atmosphere in the refrigerator which causes the balloon to be smaller.
nitrogen is the most common element in the earths atmosphere

No, because the atmosphere would pop the balloon.
It decreases.
