In a chemical change a substance undergoes a change in chemical composition. The appearance of the gold was changed in this case and not chemically combined with other elements to form new substances. Thus, this change is a physical change.
It is a chemical change, because when cotton is being woven into sheets, we cannot change sheets into cotton again, hence it is difficult to reverse.
Yes, silver can be hammered into sheets, a process known as silver sheet metalwork. The metal is heated to make it more malleable, then hammered using a technique known as planishing to create thin, flat sheets.
There are a number of metals that can be hammered into sheets, and gold is the best of them. It is the malleability of metal that allows it to be hammered thinly, and a link to that related question can be found below.
An element that can be hammered is called malleable.
It is a physical property.

This is a physical change.
No. It is a physical change because the chemical composition of the metal remains the same.

no because oxygen cannot be hammered
The fact that it can be hammered into sheets would seem to be the most relevant characteristic in this case.

Yes. Aluminium is a metal and a very malleable (can be hammered into sheets) metal as well. To prove this, 'tin' foil used to wrap food for cooking (like 'Bacofoil') is actually made from aluminum and not tin. The most malleable metal is gold - it can be hammered into thin 'gold leaf' sheets that can be so thin that they are just a few atoms thick. Aluminium is not as malleable as this, but it can easily be made into foil.
Malleability is the property that allows a material to be hammered into thin sheets without breaking.
