What are the uses of various papers?

How can flexible paper and absorbent paper- be used?

How can paper be used for writing and burning?

Flexible paper is used for printing and wrapping things. Almost all paper is flexible.

Absorbent paper is used for thingw like paper towels.

Paper is used for starting fires but does not burn well in bulk and is not generally used for power production or heating. Recycling is a better use.

I should think how one uses paper for writing is obvious
