Any bowl or utensil that is used when beating egg whites has to be perfectly clean and grease-free. When air is beaten into egg whites, the proteins of the egg white open up, which makes the whites form a semi-solid. If there are any lipids introduced into the egg whites they prevent the whites from forming a semi-solid state by surrounding the proteins of the egg whites and preventing the proteins from opening.
Dull means the appearance of the egg whites. Some stages of beating egg whites make them look shiny like patent leather. When it says dull it means like unpolished leather.
It is the fat present in the yolk. If the two gets mixed, the whites will not beat up, or if your bowl is greasy, your whites will not beat iether
Grease (or the yolk) in egg white will prevent the whites from beating up into the preferred stiffness for meringues, etc.
Beating egg whites is a physical change because it does not alter the chemical composition of the egg whites. It only changes their physical appearance and texture.
They contain calcium and that cooperates into making hard egg whites.
The egg whites don't move and you can make them into peaks. They are very stiff. Make sure you use a metal or glass bowl when beating egg whites they will beat better rather than in plastic.

beating ingredients, such as eggs etc... using the rotary egg beater, turn it in the bowl with the ingredients....
