When you whisk the egg whites, It incorporates air into it. So when it foams, that means that there is simply air in it.
When you stir the white of an egg, it becomes frothy. This is because the albumen breaks down and the egg white comes together to form a foam.
Beaten egg white foam add with sugar and a dash of lime and bake would come to a dessert name meringue. Beaten egg white foam with disinfectant was used as a wound dressing for minor burning wound. Egg white can be use for fining soup stock. Egg white whisk with water can be use for wine fining but as it was beaten, I don't think it would fit for this task.
Cream of tartar helps to stabilize the egg white foam due to the charge that the proteins in the eggs hold without it.
The process of an egg formation is called ogenesis.
Egg cartons are made from cardboard, foam and plastic depending on the needs of the egg supplier.
When you whip egg whites (albumen), you are really stretching the protein in them. As a result, they unwind and join together loosely, making them unstable. The liquid albumen forms elastic films around the air bubbles beaten into them and essentially trap them, which you can see as a foam.
When you mix it quickly, you're actually incorporating lots of tiny air bubbles into the eggs, which is why they increase in volume and become foamy.
