beating an egg is aphysical change because in order to have a chemical change, heat or some other chemical must be involed. so yes, beating an eggis a physical change
I would say a physical rather than a chemical change as the beating of the egg white and sugar will produce a thickening of the mixture suitable for baking a Meringue.
This is a physical process.
Whipping egg whites is a physical change.

-Colour -Temperature -Light -Gas produced (Bubbles) -Precipitate -Hard to reverse Examples: Cooking an egg: This is a chemical reaction for several reasons. As you cook an egg the temperature increases, also the colour of the whites change, and it is very hard to reverse. Melting a block of ice: This would not be a chemical change because it is rather known as a Physical Change. A physical change includes signs as decrease in size or change in state. In this situation the block of ice is going from a solid, to a liquid.
To do laundry for whites.
Egg whites are colourless and transparent until they are cooked when they become white and opaque. Sodium hydroxide is white.

Beating egg whites to make then stiff it is a physical change. The proteins forming the substance of the egg white are complexly folded molecules and the beating causes them to partially unravel. as they do this they can form a net which can capture tiny pockets of air which increases their volume and makes them appear white. This physical change will partially revert if the beaten whites are left to stand for too long before cooking.

both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change
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.
A good old fashioned whisk! :)
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.
They were used because of the physical differences from whites. Whites also thought that because they were not like them that had to dumber and inferior to whites.
One opposite to beating is soothing. An opposite to beating in cooking is folding. Examples: The child was so used to beatings at home, he didn't understand soothing acts. I had to beat the egg whites before folding in the sugar.
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.
