A physical change in chemistry affects the form of a substance (e.g., shape, state of matter) but not its chemical composition. The heat causes the bonds between the amino acids in the proteins to break, and as a result, new bonds are formed between different amino acids. This change in protein structure results in different properties for the cooked egg, such as increased firmness and coagulation. The truth is, no one really knows for sure. Others believe that it is endothermic, meaning that it consumes heat. The eggs appearance and chemical composition remain the same after boiling. The shell color of the colored eggs is due to pigments (ooporphins) deposited on the shell surface.
