Question

Is boiled egg a physical or chemical change?

Answer 1

Dear Student.
When you are boiling an egg the proteins in the white part of the egg gets agitated and then they start to slam into each other . Resultantly the weak bond breaks and no longer curl up . The same process goes on with the uncurled proteins and starts to form new chemical bonds . Again remember this process is irreversible .That is why boiled egg is a chemical change .
