frying an egg
boiling water
melting butter
chopping onions


Sagot :

Answer:

Frying an egg!

Explanation:

Boiling water, melting butter, and chopping onions only change the substance physically. This means that there is no chemical change happening, and even though they are in different forms, they are still the same substance.

On the other hand, frying an egg changes the chemical composition of the egg. It becomes a new substance.

Hope this helps!
