A shiny black solid was heated and formed a purple vapour which on cooling became a black solid again Is this a physical or chemical reaction and explain?
This is a physical change. The solid is Iodine, which sublimes on heating to form gaseous Iodine. When cooled, it sublimes again to form solid Iodine. Since this change is only the change of physical states, and since there's no change in the chemical structure of Iodine, this is a physical change.
