Waht do you mean "breaking down"?
Physically breaking down an egg (ie using a hammer) is a physical action.
Chemically breaking down an egg (eg in your stomach) is a chemical reaction.
Breaking down an egg during digestion is a combination of both physical and mechanical actions.
Explain what you mean.

It is a physical change.
It is because there is no chemical change to the chemical properties to the egg and the compounds.
It is only a change of physical state where the shell is broken into 2. Like seperating a pile of sand into two pile.

Breaking it is physical change, if u break with a knife,spoon etc.
but breaking with some chemicals may be a chemical change, as there would be some chemical reaction

burning a cake interior the oven is a chemical reaction, the reason being is that it truly is irreversible, that being between the residences of a chemical substitute milk going bitter interior the sunlight is likewise a chemical substitute, for the comparable reason that the reaction right it truly is irreversible. If it have been a actual substitute (like water to ice), you will possibly desire to alter it back to its unique state, while right here you are able to no longer freezing water to ice, as i discussed above, is a actual substitute, because of the fact actual transformations are basically transformations interior the state of the situation, however the situation itself maintains to be the comparable. The reaction is likewise reversible (melting ice into water). burning magnesium in a bunsen flame i think is a chemical substitute, because of the fact on of the residences of a chemical substitute is that warmth is produced, and that i think that occurs in this reaction. wish i grew to become into of help.

do you mean breaking an egg?if so braking one is a physical and cooking it would be chemical since it was in a semi liquid form changing into a solid but it is also a physical change as the yolk is almost solid in looks but if you stick a sharp object into it will become liquified but cooking it will make it solid.

Both, for inner part it is chemical reaction because fermantation starts when it brokes, for outer layer it is physical changes.
