Question

Which of the following is the best way to explain how baking a cake or frying an egg is a chemical change?

A Both are changing size and shape.
B Heat is changing the texture of both substances.
C Heat is being added to both, causing a phase change.
D The end products of both cannot be reversed to their original forms.

Answer 1

Answer: I think both are great examples of chemical changes

Explanation: because they both take and give off heat and they cant return back to their original forms

Answer 2

D or C

Step-by-step explanation:

A chemical change means that something is permanently changed and there's no way to get it back. The proteins in the egg white/yolk are subjected to high heat, they change into varying proteins.

Frying an egg is a chemical reaction. It is an example of an endothermic reaction or one that takes in heat to make the reaction occur.

When baking your cake it is a chemical change because you can't get your ingredients back. We know that it is a chemical change because heat energy is involved. When you are mixing your cake batter, it includes such ingredients as water, oil, and eggs.
