New chemical bonds are being formed, and some are being broken. A simple test for if something is a chemical change or not is if the reaction is irreversible, such as baking a cake. Quite a few chemical changes are reversible, however you can almost be certain that a physical change is reversible, such as water <-> ice.
What else can I help you with?
Baking a cake is physical change or 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.
What is a change that produces a new substance called?
A chemical change produces a new substance with different chemical properties from the original substances. This change involves the breaking and forming of chemical bonds. Examples of chemical changes include burning wood, baking a cake, and rusting of iron.
Which chemical change causes a cake to rise?
The thermal decomposition of baking powder. Baking powder is also known as sodium bi-carbonate or sodium hydrogen carbonate. When heted it undergoes thermal decomposition., releasing carbon dioxide in thre process. It is this release of CO2 that makes pastry rise when being baked.,
Is a cake that is baked in the oven a physical or chemical?
Baking a cake in the oven is a chemical change. The heat from the oven causes the chemical reactions in the ingredients (like flour, eggs, and sugar) to take place, resulting in a new substance with different properties (cake).
What causes a physical change and not a chemical change A Tearing a tissue paper B Burning a match C Baking a cake?
Tearing a tissue paper is a physical change because it involves a change in the physical state of the paper without altering its chemical composition. The other options, burning a match and baking a cake, involve chemical changes as they result in new substances being formed through chemical reactions.
How can you tell at baking a cake produces a physical change?
Baking is a chemical change because involve chemical reactions.
What is chemical reaction in baking a cake?
A cake produces a permanant colour change and a slight change in weight after baking. That means, It's a chemical reaction.

The thermal decomposition of baking powder is a chemical change.
Is baking a cake batter a chemical or physical change?
Baking a cake is a chemical property because it is going from dough to cake or batter to cake.
Why is baking a cake called a chemical change?
During baking the chemical composition of the initial ingredients is changed.
Is baking a physical or chemical change?
pretty sure its a chemical change.
