The colorful part of the balloon, the envelope, is typically made of nylon but it could be made out of many other materials such as Mylar.

Hydrogen is used. Sorry. Just regular air is used in a hot air balloon, it is heated which makes it lighter and less dense and therefore provide lift. Hence the name hot air balloon. Hydrogen is used in a gas balloon.
A typical hot air balloon is filled with the same air we breath.
A gore on a hot air balloon is a section of lightweight fabric that makes one of the panels of the balloon. The gores are cut from flat material and stitched together to give the balloon its shape.
no, hot air air is used
The gas is hot air.

A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.

A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.

yes, but when using Helium you must have the balloon completely sealed and used a mylar material for the balloon as Helium 'leaks-out' of ordinary materials.
Hot air is common.
In a liquid (as solid particles in a liquid or in a lava lamp with two immiscible liquids) In the air, hot air rises, cold air descends (as in a hot air balloon)
