Chemical or physical change

Question

Is backing a cake physical or chemical change

Answer 1

In order to bake a cake, you need to add a bunch of ingredients into a bowl that definitely do not look like a cake : eggs, flour, baking soda, butter....other stuff

The first change is a physical change before it enters the oven because all ingredients combined look different and probably smell different than the separate ingredients.

After it enters the oven, the heat triggers the baking soda to produce gas to make the cake have a puffy texture and the protein in the eggs go through a chemical change to become more firm.

So the actual process of baking a cake is both a physical and chemical change but if the question is only dealing with after the cake is in the oven , the answer is a chemical change
