Because of coagulation. This process is a denaturation of the liquid proteins, changing the secondary and tertiary structure of the proteins in a way that enhances connections between the protein strings, making them stick more firmly together and therefore changing them from liquid to solid.

Why does the egg go in to the flask when heated?

When an egg is heated, the protein present within it(the egg white), called albumin gets denatured. This is because protein structures break at high temperatures. As a result, the liquid albumin forms a thick white mass.


What is the science experiment of Egg Vacuum also knowen as Sucking an egg into a bottle and how do you do it?

Egg Vacuum For an experiment I decided to do 'Egg Vacuum'. It is a force of air that pushes the egg inside of the bottle; this is the method we used: # Find a bottle with a long, narrow neck and set it on the table. The opening should be just small enough to keep the egg from falling inside. # Boil and peel and egg. # Drop 3 lit matches into the bottle. # Quickly place the egg over the mouth of the bottle. What happens you may ask? The lit matches heat the air inside the bottle. When air is heated it expands and takes up more room. As the heated air expands, some of it escapes out the bottle. When the matches go out, the air inside the bottle cools and contracts (and takes up less room), thus creating a lower pressure inside the bottle than outside. The greater pressure outside the bottle forces the egg into the bottle. Now I'm going to tell you about Expansion, Expansion is an increase in the size of a body without the addition of material to the body. Most solids and liquids expand when they are heated and contract when they are cooled. Gases also expand when they are heated at a constant pressure. If a gas is heated in a container that prevents expansion, the pressure of the gas increases. If I wanted to get the egg out, I would simply turn the bottle upside down and blow into it. The increased air pressure in the bottle will cause the egg to pop back out. Below are some useful Related Links:
