Yes, frying an egg is a chemical change. The proteins unfold, re-bond, and turn into something brand new that you can’t undo. It’s not like melting butter (physical change) or tearing lettuce (also physical). It’s a full-on, no-turning-back transformation.
And here’s the best part: you don’t need to memorize the word “denaturation” to enjoy it. You just need to crack, fry, and eat. But now, when someone asks, “Is frying eggs a chemical change?” you can smile, point at your plate, and say, “Absolutely. And also, want some toast?”
