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.
Yes silver can be hammered into sheets.
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.
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.
Malleable , malleability is the ability of a metal to be hammered into thin sheets.
"ductility"
Physical
This is a physical change.
No. It is a physical change because the chemical composition of the metal remains the same.
Yes silver can be hammered into sheets.
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.
metals
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.
