An envelope is the bag in which the hot air is trapped ito to give the balloon lift.
I believe the word you're looking for is Ballast.
At the end of a hot air balloon flight the heated air inside is allowed to escape through a panel that is opened either in the top or side of the balloon envelope. The crew then squeezes the remaining air our of the envelope and then packs it away in a large bag ready for the next flight. This process is called deflating the balloon

When you light the burner of a hot air balloon, the balloon itself, the big bag-like part, fills with hot air which is less dense than the air in the surrounding atmosphere. The air being less dense inside means the molecules are spread apart further that normal, so it rises and, being inside the bag-like part of the balloon, it brings the balloon, the basket, and the basket's contents with it.
As the sandbag is dropped from the hot air balloon, the overall mass of the system (balloon + sandbag) decreases. This causes the average density of the system to lower, leading to a buoyant force greater than the gravitational force acting on the system, resulting in the balloon rising.
get a bag and jump off a cliff

because the air inside the balloon take up the space and it will not allow the balloon to fit in bag
No a balloon carry lighter weight then a plastic bag.
Urine bag
As the bag of balloon rises, the pressure inside the bag of balloon decreases. Air pressure generally decreases as the altitude increases.
A basket and a bag supported with wires for the balloon part
there is no way to make a balloon from scratch, but you could use a subsitute for a balloon insted. maybe a plastic bag?
a balloon
593 meters.
Balloon boy
Yes.
