Yes it is.
Because when you cook, you cant get your ingredients back !

a physical change is reversible like freezing or melting but a chemical change is irreversible like baking a cake, once it's been cooked, you can't get your cake mix bake
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
Yes, because the chemical reaction of rust is next to impossible to get the iron, water and oxygen back from the iron oxide it creates by rusting, and its like baking a cake is a chemical reaction, once the cake is a cake you can't get the eggs or sugar back. The rust also makes the nails weak and flimsy, this is why we shouldn't use nails if they are rusted, especially large structures. A way you can tell its a chemical reaction is that the color changes and the appearance changes.
It is a chemical change. Here oxidation of Iron occurs and being oxidation reaction, it is 'exothermic' reaction.Through it takes prolonged period and it is difficult to observe it, you can deduct it. As 'all' oxidation reactions are 'exothermic'.
Chemical - a physical change can be reversed , e.g Freezing water, melting chocolate. But something like popping corn is ireversible like baking a cake or boiling a egg. Hope this helps.

Baking a cake is a chemical property because it is going from dough to cake or batter to cake.
Yes, because the simplified definition of a 'chemical change or reaction' is "a change or reaction (usually dealing with extreme heat or cold) that CAN NOT be undone. Thus, a cooked cake can not be changed back to its originall state of batter.Hope I helped :)
It depends on how the cake was before it was heated. If the cake was raw to begin with and the cake is baked, then yes, it is a chemical change because yeast is making the cake rise. If it was an already baked cake and you are just heating it, then I am not so sure. I don't think it changes at all. Then again, if you are burning the cake, I guess it is a chemical change because fire is making it burn.
Chemical change.
Baking a cake is a chemical change because the ingredients undergo a chemical reaction when exposed to heat, resulting in a transformation of their molecular structure to form the cake. This is different from a physical change, which does not alter the composition of the ingredients.
Baking is all about Chemical Changes. The reason cake batter turns into a cake is because of chemical reactions.
Baking is a chemical change because involve chemical reactions.
Yes. This is because when the cake is baked, chemicals help it rise, making this a chemical change. Making the icing is a different story. It is a physical change.
Because when you bake a cake, you cant take the ingredients back. And when you bake it, the chemicals rise, making it a Chemical Change.
no. frying an egg is not physical, because once you turn the egg into a solid, you cant change it back to a liquidish substance. Heating is a chemical change, so there for, frying an egg is a chemical change. Same with baking a cake. Once you add heat to a substance, like cakebatter, you cant change it back into cake batter there for making it a chemical change.
no it is not, it is a chemical and irreversible change,
