There are a couple different things that can happen when heat is applied to an egg. If the heat is applied through boiling water you can hard boil the egg in its shell. If it is applied from a pan you can scramble, fry, or even create over easy eggs. It depends on what you are looking for as an end result, in general though heat will cook an egg.
it becomes a solid, so that you can eat it.
Normally the albumin in the egg results in a mass of thick, white. This is due to its protein structures which will snap or break at a high temperature.
Spoilage. Or maybe they'd cook inside the shell...
denaturation of egg protein. cooking (increased temperature) breaks the bonds in the secondary and tertiary structures of the protein in eggs.
When an egg is cooked, the heat changes the molecular structure, changing from liquid to solid as the protein molecules form an irreversible colloid.
this fails
Convection occurs when heat is transferred into an object through motion or movement; an example would be boiling water.

No where coldness is transferred. Only heat would be transferred. Even ice could not pass coldness to your hands as you hold it. Actually you lose heat right from your hand and so you feel cold.
conduction
No; having part of an egg come out of the shell while boiling does not mean the egg was bad. It means the heat caused the bubble of air inside the egg to expand, cracking the shell, and allowing a bit of the egg white to escape.
Yes, Conduction is illustrated by the heat being transferred from the hot pan into the egg which then causes the egg to heat and transform.
It is endothermic as the water mus gain energy to go from a liquid to a gas.
as long as the shell doesn't crack no. Adding heat to something wont change its mass unless something is added or taken away from the egg
It's done with an electrical element inside the tank.It's the same principle as boiling water in an electric jug.Hope this helps.
Salt - an impurity - elevates the boiling point of water. Egg will be cooking at a temperature higher than 100 degrees celsius.Denaturation of protein/cooking of egg will occur in less time.
Yes, by boiling an egg, the shell will be damaged when an object is inserted into the shell or the egg.
