A physical change does not alter the chemical nature of the substance. Freezing of water to form ice (solid state) H2O(l) => H2O(s) only changes state of existance but not its chemistry.
A chemical change alters the chemical nature of the substance producing new substances with different properties than the ones it was formed from.
Reaction of 2H2(g) + O2(g) => 2H2O is a chemical change where properties of water are different than properties of molecular hydrogen and oxygen.
So, for your question, the act of breaking an egg is a physical change because the product (broken egg) doesn't change chemically into a different substance. However, cooking an egg (all methods) gives substances with different chemical and physical properties and is a chemical change.
Can anyone, a experienced person tell whether breaking of an egg is chemical or a physical change.. Coz no one has given a expected answer... Plz do it with interest coz if you don't know it don't reply... Someone has put tested, someone has put cooking.. What is all that.. So plz reply.. Thank you
