Typically a type of ripstop nylon with a silicone backing is used, along with Nomex fabric at the base of the balloon.
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 hot air balloon can be used for weddings, commercial, and just plain leisure. It can also be used to observe an enemy or drop bombs on them.
A typical hot air balloon is filled with the same air we breath.
Helium gas is used in a balloon vendor.

The gas is hot air.
This depends on many variables. What is the weight of the notebook, what is the diameter of the balloon, what material is used for the balloon, what gas is used to fill the balloon, what is the weight of the material that is attached to the balloon and the notebook, is this taking place in earth's atmosphere, or somewhere else. There are several other minor variables, as well. And do remember, the balloon must be filled with a gas that is lighter than the surrounding medium!
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
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.
Gore-Tex is the correct spelling. Gore-Tex is a type of fabric registered in 1969 by the company W. L. Gore and Associates, and used mainly for clothing.
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.

Gore-Tex is a water-proofing material, a chemically inert form of expanded polytetrafluoroethylene (PTFE, or Teflon). Gore-tex is one of the most versatile waterproofing laminates used for clothing and shoes. When the outside gets wet, the inside will stay dry due to the breathable Gore-Tex lining.
